!  Copyright (C) 1989, 1991 Free Software Foundation, Inc.
!      59 Temple Place, Suite 330, Boston, MA  02111-1307  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
! 
! 	    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) <year>  <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., 59 Temple Place, Suite 330, Boston, MA  02111-1307  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) year  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, and a
! file `config.log' containing compiler output (useful mainly for
! debugging `configure').
! 
!    It can also use an optional file (typically called `config.cache'
! and enabled with `--cache-file=config.cache' or simply `-C') that saves
! the results of its tests to speed up reconfiguring.  (Caching is
! disabled by default to prevent problems with accidental use of stale
! cache files.)
! 
!    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 you are using the cache, and at
! some point `config.cache' contains results you don't want to keep, you
! may remove or edit it.
! 
!    The file `configure.ac' (or `configure.in') is used to create
! `configure' by a program called `autoconf'.  You only need
! `configure.ac' 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.  Run `./configure --help'
! for details on some of the pertinent environment variables.
! 
!    You can give `configure' initial values for configuration parameters
! by setting variables in the command line or in the environment.  Here
! is an example:
! 
!      ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
! 
!    *Note Defining Variables::, for more details.
! 
! 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 support 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' cannot figure out
! automatically, but needs to determine by the type of machine the package
! will run on.  Usually, assuming the package is built to be run on the
! _same_ architectures, `configure' can figure that out, but if it prints
! a message saying it cannot guess the machine type, give it the
! `--build=TYPE' option.  TYPE can either be a short name for the system
! type, such as `sun4', or a canonical name which has the form:
! 
!      CPU-COMPANY-SYSTEM
! 
! where SYSTEM can have one of these forms:
! 
!      OS KERNEL-OS
! 
!    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 machine type.
! 
!    If you are _building_ compiler tools for cross-compiling, you should
! use the `--target=TYPE' option to select the type of system they will
! produce code for.
! 
!    If you want to _use_ a cross compiler, that generates code for a
! platform different from the build platform, you should specify the
! "host" platform (i.e., that on which the generated programs will
! eventually be run) with `--host=TYPE'.
! 
! 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.
! 
! Defining Variables
! ==================
! 
!    Variables not defined in a site shell script can be set in the
! environment passed to `configure'.  However, some packages may run
! configure again during the build, and the customized values of these
! variables may be lost.  In order to avoid this problem, you should set
! them in the `configure' command line, using `VAR=value'.  For example:
! 
!      ./configure CC=/usr/local2/bin/gcc
! 
! will cause the specified gcc to be used as the C compiler (unless it is
! overridden in the site shell script).
! 
! `configure' Invocation
! ======================
! 
!    `configure' recognizes the following options to control how it
! operates.
! 
! `--help'
! `-h'
!      Print a summary of the options to `configure', and exit.
! 
! `--version'
! `-V'
!      Print the version of Autoconf used to generate the `configure'
!      script, and exit.
! 
! `--cache-file=FILE'
!      Enable the cache: use and save the results of the tests in FILE,
!      traditionally `config.cache'.  FILE defaults to `/dev/null' to
!      disable caching.
! 
! `--config-cache'
! `-C'
!      Alias for `--cache-file=config.cache'.
! 
! `--quiet'
! `--silent'
! `-q'
!      Do not print messages saying which checks are being made.  To
!      suppress all normal output, redirect it to `/dev/null' (any error
!      messages will still be shown).
! 
! `--srcdir=DIR'
!      Look for the package's source code in directory DIR.  Usually
!      `configure' can determine that directory automatically.
! 
! `configure' also accepts some other, not widely useful, options.  Run
! `configure --help' for more details.
