+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                          675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+GNU make NEWS -- history of user-visible changes.  11 December 1995
+
+Copyright (C) 1992, 1993, 1994, 1995 Free Software Foundation, Inc.
+See the end for copying conditions.
+
+Please send GNU make bug reports to bug-gnu-utils@prep.ai.mit.edu.
+
+Version 3.75
+
+* The directory messages printed by `-w' and implicitly in sub-makes,
+  are now omitted if Make runs no commands and has no other messages to print.
+
+Version 3.73
+
+* Converted to use Autoconf version 2, so `configure' has some new options.
+  See INSTALL for details.
+
+* You can now send a SIGUSR1 signal to Make to toggle printing of debugging
+  output enabled by -d, at any time during the run.
+
+Version 3.72
+
+* DJ Delorie has ported Make to MS-DOS using the GO32 extender.
+  He is maintaining the DOS port, not the GNU Make maintainer;
+  please direct bugs and questions for DOS to <djgpp@sun.soe.clarkson.edu>.
+  MS-DOS binaries are available for FTP from oak.oakland.edu:pub/msdos/djgpp.
+
+* The `MAKEFLAGS' variable (in the environment or in a makefile) can now
+  contain variable definitions itself; these are treated just like
+  command-line variable definitions.  Make will automatically insert any
+  variable definitions from the environment value of `MAKEFLAGS' or from
+  the command line, into the `MAKEFLAGS' value exported to children.  The
+  `MAKEOVERRIDES' variable previously included in the value of `$(MAKE)'
+  for sub-makes is now included in `MAKEFLAGS' instead.  As before, you can
+  reset `MAKEOVERRIDES' in your makefile to avoid putting all the variables
+  in the environment when its size is limited.
+
+* If `.DELETE_ON_ERROR' appears as a target, Make will delete the target of
+  a rule if it has changed when its commands exit with a nonzero status,
+  just as when the commands get a signal.
+
+* The automatic variable `$+' is new.  It lists all the dependencies like
+  `$^', but preserves duplicates listed in the makefile.  This is useful
+  for linking rules, where library files sometimes need to be listed twice
+  in the link order.
+
+* You can now specify the `.IGNORE' and `.SILENT' special targets with
+  dependencies to limit their effects to those files.  If a file appears as
+  a dependency of `.IGNORE', then errors will be ignored while running the
+  commands to update that file.  Likewise if a file appears as a dependency
+  of `.SILENT', then the commands to update that file will not be printed
+  before they are run.  (This change was made to conform to POSIX.2.)
+
+Version 3.71
+
+* The automatic variables `$(@D)', `$(%D)', `$(*D)', `$(<D)', `$(?D)', and
+  `$(^D)' now omit the trailing slash from the directory name.  (This change
+  was made to comply with POSIX.2.)
+
+* The source distribution now includes the Info files for the Make manual.
+  There is no longer a separate distribution containing Info and DVI files.
+
+* You can now set the variables `binprefix' and/or `manprefix' in
+  Makefile.in (or on the command line when installing) to install GNU make
+  under a name other than `make' (i.e., ``make binprefix=g install''
+  installs GNU make as `gmake').
+
+* The built-in Texinfo rules use the new variables `TEXI2DVI_FLAGS' for
+  flags to the `texi2dvi' script, and `MAKEINFO_FLAGS' for flags to the
+  Makeinfo program.
+
+* The exit status of Make when it runs into errors is now 2 instead of 1.
+  The exit status is 1 only when using -q and some target is not up to date.
+  (This change was made to comply with POSIX.2.)
+
+Version 3.70
+
+* It is no longer a fatal error to have a NUL character in a makefile.
+  You should never put a NUL in a makefile because it can have strange
+  results, but otherwise empty lines full of NULs (such as produced by
+  the `xmkmf' program) will always work fine.
+
+* The error messages for nonexistent included makefiles now refer to the
+  makefile name and line number where the `include' appeared, so Emacs's
+  C-x ` command takes you there (in case it's a typo you need to fix).
+
+Version 3.69
+
+* Implicit rule search for archive member references is now done in the
+  opposite order from previous versions: the whole target name `LIB(MEM)'
+  first, and just the member name and parentheses `(MEM)' second.
+
+* Make now gives an error for an unterminated variable or function reference.
+  For example, `$(foo' with no matching `)' or `${bar' with no matching `}'.
+
+* The new default variable `MAKE_VERSION' gives the version number of
+  Make, and a string describing the remote job support compiled in (if any).
+  Thus the value (in this release) is something like `3.69' or `3.69-Customs'.
+
+* Commands in an invocation of the `shell' function are no longer run with
+  a modified environment like target commands are.  As in versions before
+  3.68, they now run with the environment that `make' started with.  We
+  have reversed the change made in version 3.68 because it turned out to
+  cause a paradoxical situation in cases like:
+
+	export variable = $(shell echo value)
+
+  When Make attempted to put this variable in the environment for a target
+  command, it would try expand the value by running the shell command
+  `echo value'.  In version 3.68, because it constructed an environment
+  for that shell command in the same way, Make would begin to go into an
+  infinite loop and then get a fatal error when it detected the loop.
+
+* The commands given for `.DEFAULT' are now used for phony targets with no
+  commands.
+
+Version 3.68
+
+* You can list several archive member names inside parenthesis:
+  `lib(mem1 mem2 mem3)' is equivalent to `lib(mem1) lib(mem2) lib(mem3)'.
+
+* You can use wildcards inside archive member references.  For example,
+  `lib(*.o)' expands to all existing members of `lib' whose names end in
+  `.o' (e.g. `lib(a.o) lib(b.o)'); `*.a(*.o)' expands to all such members
+  of all existing files whose names end in `.a' (e.g. `foo.a(a.o)
+  foo.a(b.o) bar.a(c.o) bar.a(d.o)'.
+
+* A suffix rule `.X.a' now produces two pattern rules:
+	(%.o): %.X	# Previous versions produced only this.
+	%.a: %.X	# Now produces this as well, just like other suffixes.
+
+* The new flag `--warn-undefined-variables' says to issue a warning message
+  whenever Make expands a reference to an undefined variable.
+
+* The new `-include' directive is just like `include' except that there is
+  no error (not even a warning) for a nonexistent makefile.
+
+* Commands in an invocation of the `shell' function are now run with a
+  modified environment like target commands are, so you can use `export' et
+  al to set up variables for them.  They used to run with the environment
+  that `make' started with.
+
+Version 3.66
+
+* `make --version' (or `make -v') now exits immediately after printing
+  the version number.
+
+Version 3.65
+
+* Make now supports long-named members in `ar' archive files.
+
+Version 3.64
+
+* Make now supports the `+=' syntax for a variable definition which appends
+  to the variable's previous value.  See the section `Appending More Text
+  to Variables' in the manual for full details.
+
+* The new option `--no-print-directory' inhibits the `-w' or
+  `--print-directory' feature.  Make turns on `--print-directory'
+  automatically if you use `-C' or `--directory', and in sub-makes; some
+  users have found this behavior undesirable.
+
+* The built-in implicit rules now support the alternative extension
+  `.txinfo' for Texinfo files, just like `.texinfo' and `.texi'.
+
+Version 3.63
+
+* Make now uses a standard GNU `configure' script.  See the new file
+  INSTALL for the new (and much simpler) installation procedure.
+
+* There is now a shell script to build Make the first time, if you have no
+  other `make' program.  `build.sh' is created by `configure'; see README.
+
+* GNU Make now completely conforms to the POSIX.2 specification for `make'.
+
+* Elements of the `$^' and `$?' automatic variables that are archive
+  member references now list only the member name, as in Unix and POSIX.2.
+
+* You should no longer ever need to specify the `-w' switch, which prints
+  the current directory before and after Make runs.  The `-C' switch to
+  change directory, and recursive use of Make, now set `-w' automatically.
+
+* Multiple double-colon rules for the same target will no longer have their
+  commands run simultaneously under -j, as this could result in the two
+  commands trying to change the file at the same time and interfering with
+  one another.
+
+* The `SHELL' variable is now never taken from the environment.
+  Each makefile that wants a shell other than the default (/bin/sh) must
+  set SHELL itself.  SHELL is always exported to child processes.
+  This change was made for compatibility with POSIX.2.
+
+* Make now accepts long options.  There is now an informative usage message
+  that tells you what all the options are and what they do.  Try `make --help'.
+
+* There are two new directives: `export' and `unexport'.  All variables are
+  no longer automatically put into the environments of the commands that
+  Make runs.  Instead, only variables specified on the command line or in
+  the environment are exported by default.  To export others, use:
+	export VARIABLE
+  or you can define variables with:
+	export VARIABLE = VALUE
+  or:
+	export VARIABLE := VALUE
+  You can use just:
+	export
+  or:
+	.EXPORT_ALL_VARIABLES:
+  to get the old behavior.  See the node `Variables/Recursion' in the manual
+  for a full description.
+
+* The commands from the `.DEFAULT' special target are only applied to
+  targets which have no rules at all, not all targets with no commands.
+  This change was made for compatibility with Unix make.
+
+* All fatal error messages now contain `***', so they are easy to find in
+  compilation logs.
+
+* Dependency file names like `-lNAME' are now replaced with the actual file
+  name found, as with files found by normal directory search (VPATH).
+  The library file `libNAME.a' may now be found in the current directory,
+  which is checked before VPATH; the standard set of directories (/lib,
+  /usr/lib, /usr/local/lib) is now checked last.
+  See the node `Libraries/Search' in the manual for full details.
+
+* A single `include' directive can now specify more than one makefile to
+  include, like this:
+	include file1 file2
+  You can also use shell file name patterns in an `include' directive:
+	include *.mk
+
+* The default directories to search for included makefiles, and for
+  libraries specified with `-lNAME', are now set by configuration.
+
+* You can now use blanks as well as colons to separate the directories in a
+  search path for the `vpath' directive or the `VPATH' variable.
+
+* You can now use variables and functions in the left hand side of a
+  variable assignment, as in "$(foo)bar = value".
+
+* The `MAKE' variable is always defined as `$(MAKE_COMMAND) $(MAKEOVERRIDES)'.
+  The `MAKE_COMMAND' variable is now defined to the name with which make
+  was invoked.
+
+* The built-in rules for C++ compilation now use the variables `$(CXX)' and
+  `$(CXXFLAGS)' instead of `$(C++)' and `$(C++FLAGS)'.  The old names had
+  problems with shells that cannot have `+' in environment variable names.
+
+* The value of a recursively expanded variable is now expanded when putting
+  it into the environment for child processes.  This change was made for
+  compatibility with Unix make.
+
+* A rule with no targets before the `:' is now accepted and ignored.
+  This change was made for compatibility with SunOS 4 make.
+  We do not recommend that you write your makefiles to take advantage of this.
+
+* The `-I' switch can now be used in MAKEFLAGS, and are put there
+  automatically just like other switches.
+
+Version 3.61
+
+* Built-in rules for C++ source files with the `.C' suffix.
+  We still recommend that you use `.cc' instead.
+
+* If commands are given too many times for a single target,
+  the last set given is used, and a warning message is printed.
+
+* Error messages about makefiles are in standard GNU error format,
+  so C-x ` in Emacs works on them.
+
+* Dependencies of pattern rules which contain no % need not actually exist
+  if they can be created (just like dependencies which do have a %).
+
+Version 3.60
+
+* A message is always printed when Make decides there is nothing to be done.
+  It used to be that no message was printed for top-level phony targets
+  (because "`phony' is up to date" isn't quite right).  Now a different
+  message "Nothing to be done for `phony'" is printed in that case.
+
+* Archives on AIX now supposedly work.
+
+* When the commands specified for .DEFAULT are used to update a target,
+  the $< automatic variable is given the same value as $@ for that target.
+  This is how Unix make behaves, and this behavior is mandated by POSIX.2.
+
+Version 3.59
+
+* The -n, -q, and -t options are not put in the `MAKEFLAGS' and `MFLAG'
+  variables while remaking makefiles, so recursive makes done while remaking
+  makefiles will behave properly.
+
+* If the special target `.NOEXPORT' is specified in a makefile,
+  only variables that came from the environment and variables
+  defined on the command line are exported.
+
+Version 3.58
+
+* Suffix rules may have dependencies (which are ignored).
+
+Version 3.57
+
+* Dependencies of the form `-lLIB' are searched for as /usr/local/lib/libLIB.a
+  as well as libLIB.a in /usr/lib, /lib, the current directory, and VPATH.
+
+Version 3.55
+
+* There is now a Unix man page for GNU Make.  It is certainly not a replacement
+for the Texinfo manual, but it documents the basic functionality and the
+switches.  For full documentation, you should still read the Texinfo manual.
+Thanks to Dennis Morse of Stanford University for contributing the initial
+version of this.
+
+* Variables which are defined by default (e.g., `CC') will no longer be put
+into the environment for child processes.  (If these variables are reset by the
+environment, makefiles, or the command line, they will still go into the
+environment.)
+
+* Makefiles which have commands but no dependencies (and thus are always
+  considered out of date and in need of remaking), will not be remade (if they
+  were being remade only because they were makefiles).  This means that GNU
+  Make will no longer go into an infinite loop when fed the makefiles that
+  `imake' (necessary to build X Windows) produces.
+
+* There is no longer a warning for using the `vpath' directive with an explicit
+pathname (instead of a `%' pattern).
+
+Version 3.51
+
+* When removing intermediate files, only one `rm' command line is printed,
+listing all file names.
+
+* There are now automatic variables `$(^D)', `$(^F)', `$(?D)', and `$(?F)'.
+These are the directory-only and file-only versions of `$^' and `$?'.
+
+* Library dependencies given as `-lNAME' will use "libNAME.a" in the current
+directory if it exists.
+
+* The automatic variable `$($/)' is no longer defined.
+
+* Leading `+' characters on a command line make that line be executed even
+under -n, -t, or -q (as if the line contained `$(MAKE)').
+
+* For command lines containing `$(MAKE)', `${MAKE}', or leading `+' characters,
+only those lines are executed, not their entire rules.
+(This is how Unix make behaves for lines containing `$(MAKE)' or `${MAKE}'.)
+
+Version 3.50
+
+* Filenames in rules will now have ~ and ~USER expanded.
+
+* The `-p' output has been changed so it can be used as a makefile.
+(All information that isn't specified by makefiles is prefaced with comment
+characters.)
+
+Version 3.49
+
+* The % character can be quoted with backslash in implicit pattern rules,
+static pattern rules, `vpath' directives, and `patsubst', `filter', and
+`filter-out' functions.  A warning is issued if a `vpath' directive's
+pattern contains no %.
+
+* The `wildcard' variable expansion function now expands ~ and ~USER.
+
+* Messages indicating failed commands now contain the target name:
+	make: *** [target] Error 1
+
+* The `-p' output format has been changed somewhat to look more like
+makefile rules and to give all information that Make has about files.
+
+Version 3.48
+
+Version 3.47
+
+* The `-l' switch with no argument removes any previous load-average limit.
+
+* When the `-w' switch is in effect, and Make has updated makefiles,
+it will write a `Leaving directory' messagfe before re-executing itself.
+This makes the `directory change tracking' changes to Emacs's compilation
+commands work properly.
+
+Version 3.46
+
+* The automatic variable `$*' is now defined for explicit rules,
+as it is in Unix make.
+
+Version 3.45
+
+* The `-j' switch is now put in the MAKEFLAGS and MFLAGS variables when
+specified without an argument (indicating infinite jobs).
+The `-l' switch is not always put in the MAKEFLAGS and MFLAGS variables.
+
+* Make no longer checks hashed directories after running commands.
+The behavior implemented in 3.41 caused too much slowdown.
+
+Version 3.44
+
+* A dependency is NOT considered newer than its dependent if
+they have the same modification time.  The behavior implemented
+in 3.43 conflicts with RCS.
+
+Version 3.43
+
+* Dependency loops are no longer fatal errors.
+
+* A dependency is considered newer than its dependent if
+they have the same modification time.
+
+Version 3.42
+
+* The variables F77 and F77FLAGS are now set by default to $(FC) and
+$(FFLAGS).  Makefiles designed for System V make may use these variables in
+explicit rules and expect them to be set.  Unfortunately, there is no way to
+make setting these affect the Fortran implicit rules unless FC and FFLAGS
+are not used (and these are used by BSD make).
+
+Version 3.41
+
+* Make now checks to see if its hashed directories are changed by commands.
+Other makes that hash directories (Sun, 4.3 BSD) don't do this.
+
+Version 3.39
+
+* The `shell' function no longer captures standard error output.
+
+Version 3.32
+
+* A file beginning with a dot can be the default target if it also contains
+a slash (e.g., `../bin/foo').  (Unix make allows this as well.)
+
+Version 3.31
+
+* Archive member names are truncated to 15 characters.
+
+* Yet more USG stuff.
+
+* Minimal support for Microport System V (a 16-bit machine and a
+brain-damaged compiler).  This has even lower priority than other USG
+support, so if it gets beyond trivial, I will take it out completely.
+
+* Revamped default implicit rules (not much visible change).
+
+* The -d and -p options can come from the environment.
+
+Version 3.30
+
+* Improved support for USG and HPUX (hopefully).
+
+* A variable reference like `$(foo:a=b)', if `a' contains a `%', is
+equivalent to `$(patsubst a,b,$(foo))'.
+
+* Defining .DEFAULT with no deps or commands clears its commands.
+
+* New default implicit rules for .S (cpp, then as), and .sh (copy and make
+executable).  All default implicit rules that use cpp (even indirectly), use
+$(CPPFLAGS).
+
+Version 3.29
+
+* Giving the -j option with no arguments gives you infinite jobs.
+
+Version 3.28
+
+* New option: "-l LOAD" says not to start any new jobs while others are
+running if the load average is not below LOAD (a floating-point number).
+
+* There is support in place for implementations of remote command execution
+in Make.  See the file remote.c.
+
+Version 3.26
+
+* No more than 10 directories will be kept open at once.
+(This number can be changed by redefining MAX_OPEN_DIRECTORIES in dir.c.)
+
+Version 3.25
+
+* Archive files will have their modification times recorded before doing
+anything that might change their modification times by updating an archive
+member.
+
+Version 3.20
+
+* The `MAKELEVEL' variable is defined for use by makefiles.
+
+Version 3.19
+
+* The recursion level indications in error messages are much shorter than
+they were in version 3.14.
+
+Version 3.18
+
+* Leading spaces before directives are ignored (as documented).
+
+* Included makefiles can determine the default goal target.
+(System V Make does it this way, so we are being compatible).
+
+Version 3.14.
+
+* Variables that are defaults built into Make will not be put in the
+environment for children.  This just saves some environment space and,
+except under -e, will be transparent to sub-makes.
+
+* Error messages from sub-makes will indicate the level of recursion.
+
+* Hopefully some speed-up for large directories due to a change in the
+directory hashing scheme.
+
+* One child will always get a standard input that is usable.
+
+* Default makefiles that don't exist will be remade and read in.
+
+Version 3.13.
+
+* Count parentheses inside expansion function calls so you can
+have nested calls: `$(sort $(foreach x,a b,$(x)))'.
+
+Version 3.12.
+
+* Several bug fixes, including USG and Sun386i support.
+
+* `shell' function to expand shell commands a la `
+
+* If the `-d' flag is given, version information will be printed.
+
+* The `-c' option has been renamed to `-C' for compatibility with tar.
+
+* The `-p' option no longer inhibits other normal operation.
+
+* Makefiles will be updated and re-read if necessary.
+
+* Can now run several commands at once (parallelism), -j option.
+
+* Error messages will contain the level of Make recursion, if any.
+
+* The `MAKEFLAGS' and `MFLAGS' variables will be scanned for options after
+makefiles are read.
+
+* A double-colon rule with no dependencies will always have its commands run.
+(This is how both the BSD and System V versions of Make do it.)
+
+Version 3.05
+
+(Changes from versions 1 through 3.05 were never recorded.  Sorry.)

+This directory contains the 3.74.1 test release of GNU Make.
+All bugs reported for previous test releases have been fixed.
+Some bugs surely remain.
+
+For general building and installation instructions, see the file INSTALL.
+If you need to build GNU Make and have no other `make' program to use,
+you can use the shell script `build.sh' instead.  To do this, first run
+`configure' as described in INSTALL.  Then, instead of typing `make' to
+build the program, type `sh build.sh'.  This should compile the program
+in the current directory.  Then you will have a Make program that you can
+use for `make install', or whatever else.
+
+Some systems' Make programs are broken and cannot process the Makefile for
+GNU Make.  If you get errors from your system's Make when building GNU
+Make, try using `build.sh' instead.
+
+It has been reported that the XLC 1.2 compiler on AIX 3.2 is buggy such
+that if you compile make with `cc -O' on AIX 3.2, it will not work correctly.
+It is said that using `cc' without `-O' does work.
+
+One area that is often a problem in configuration and porting is the code
+to check the system's current load average.  To make it easier to test and
+debug this code, you can do `make check-loadavg' to see if it works
+properly on your system.  (You must run `configure' beforehand, but you
+need not build Make itself to run this test.)
+
+See the file NEWS for what has changed since previous releases.
+
+GNU Make is fully documented in make.texinfo.  See the section entitled
+`Problems and Bugs' for information on submitting bug reports.
+
+GNU Make is free software.  See the file COPYING for copying conditions.

+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+                    675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License").  Each licensee is
+addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    c) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    d) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+     Appendix: How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Library General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Library General Public License for more details.
+
+    You should have received a copy of the GNU Library General Public
+    License along with this library; if not, write to the Free
+    Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
