+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ 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.

+
+                              hacking
+
+  build basics
+
+   One of the coolest things about rvs (imo) is how modular and
+   customizable it is.  If you wish to create a fork of rvs, it wls ould
+   be a good idea to give it a different name.  This can be done
+   without even changing a single source file!  Simply run configure
+   with `--name=NAME' option (variables that have `rvs' in the name
+   will not be renamed, but the user will never know this unless they
+   peek ath the code).
+   
+   Other options to configure and their default values are:
+   	name='rvs'
+   		The name of the program. Note that unlike most
+   		variables, you should NOT call this in Makefiles
+   		(`$(name)'), but use `$(rvs)' instead.
+   	RVS='$(bindir)/$(rvs)'
+   		Where the exectuable will be. `$(rvs)' is the same as
+   		`$(name)' (see above). In this document it is
+   		sometimes reffered to as the `wrapper'.
+   	SHELL='/bin/sh'
+   		The shell that will be used by make, and the shell
+   		that scripts will run in. (Perhaps we should make
+   		these separate variables?)
+   	prefix='/usr/local'
+   		Standard GNU variable. Many of you will want to
+   		change this to `/usr', or `/home/USER_NAME'
+   	exec_prefix='$(prefix)'
+   		Standard GNU variable.
+   	bindir='$(exec_prefix)/bin'
+   		Standard GNU variable.
+   	sbindir='$(exec_prefix)/sbin'
+   		Standard GNU variable.
+   	libexecdir='$(exec_prefix)/libexec'
+   		Standard GNU variable.  The plugins will be installed
+   		at $(libexecdir)/$(name)
+   	srcdir=$(readlink -f `dirname "$0"`)
+   		Where the source code is.  The default value evaluates
+   		to the directory of the `configure' script.
+   
+   These can either be changed by manually changing `configure' or by
+   running it like:
+   	./configure --VAR_NAME=VALUE
+   
+   In this document, the `$(VAR_NAME)' refers to whatever you set the
+   value to.
+   
+   The configure script will run on any instance of `Makefile.in' in
+   $(srcdir).
+   
+   Currently, rvs is distributed with 2 pluggins. `repo'(sitory) is
+   the core of the rvs file database. `users' handles all usernames,
+   settings, and other info.
+
+  commands
+
+   By itself, rvs does almost nothing.  All real functionality is
+   provided by plugins.  When you invoke rvs, you do so in the format
+   `rvs COMMAND'. Plugins work by adding new commands.
+
+   Most commands are provided by plugins, however, a few are built in:
+      init
+      	Initializes a repository in the current directory. It creates
+      	`./.$(name)', and runs any initalizers for
+      	plugins.
+      install PLUGIN DIR
+      	Installs PLUGIN, for which the files are found in DIR. Unless
+      	an older version is already installed, it adds the plugin to
+      	have lowest priority (see `$(libexecdir)/$(rvs)/plugins').
+      uninstall PLUGIN
+      	Uninstalls PLUGIN. Did that really need to be said?
+   
+   A plugin is simply a collection of independant executable files.
+   When rvs is invoked, it looks for the COMMAND in a few places:
+     1) checks if COMMAND is an built-in command
+     2) looks at the file `$(libexecdir)/$(rvs)/plugins'. This is a
+        newline-delimited list of plugin names.
+     3) loops through the directories `$(libexecdir)/$(rvs)/PLUGIN',
+        where PLUGIN is one of the values in
+        `$(libexecdir)/$(rvs)/plugins', in the order they appear in
+        the file.
+     4) if rvs does not find the command, it reports an error
+   
+   
+   If you would like to contribute a plugin, or distribute one with a
+   fork, all you have to do is put it in `$(srcdir)/plugins/NAME'. The
+   main Makefile will recognize any directory in `$(srcdir)/plugins/'
+   as a plugin, and will run `make -C `plugins/NAME/Makefile'. It
+   should create a directory (mine use `plugins/NAME/out') to put ALL,
+   and ONLY the final files to be used by that plugin. 
+   
+========this is outdated but I don't really want to keep editing it ==
+
+  build system
+
+   The build system rvs uses is rather simple.
+   `./configure' does two things:
+   	* create a sed script (`var.sed')
+   	* run every incance of `$(srcdir)/Makefile.in' through
+   	  `var.sed' to generate a propper `Makefile'
+
+    `var.sed' contains all configuration variables. When it processes
+    a file every instance of `@VAR_NAME@' is replaced by that
+    variable's value. This makes `configure' act much like a GNU
+    package `congfigure'. Note that this replacement only happens for
+    defined variables.
+
+   Most of these can easily be changed _after_ `compilation' also:
+   	VER       	line 4 of the wrapper
+   	SHELL     	line 1 of each shell script
+   	prefix    	simply move the wrapper
+   	bindir    	simply move the wrapper
+   	libexecdir	move the directory, then update the line
+   	           	`RVSDIR=...' in the wrapper
+   
+   I have designed this system to be extremely modular. As you may
+   have figured out, each bit on functionality is in it's own
+   executable, and the file you call when you type `rvs' is just a
+   wrapper for them.
+
+   The wrapper is quite simple in mechanism. It simply checks if
+   `$$libdir$$/COMMAND_NAME' exists, and if so, runs that file.
+   
+   The `rvs commit' command is also quite simple in design. It takes a
+   single argument; the file to commit. If no target is specified, it
+   defaults to `./'. It checks which type of file the target is, and
+   runs `rvs commit.FILE_CODE TARGET'. The file codes are as follows:
+   
+   	block       (buffered) special b
+   	character (unbuffered) special c
+   	directory                      d
+   	named pipe (FIFO)              p
+   	regular file                   f
+   	symbolic link                  l
+   	socket                         s
+   	door (Solaris only)            D
+
+   As you probably noticed (if you've looked at the blueprints or
+   source files), only directories and regular files have been
+   implemented as of rvs 0.7.0.
+   
+   After `rvs commit' has done this, it creates a meta-file for that
+   commit. The meta file contains author, copyright owner, licence
+   data, file permissions, timestamps, etc. The id of the meta-file is
+   written to stdout, and used to later check out that commit.
+
+   get works in much the same way as commit, only it reads the file
+   type from the meta-file, then runs `rvs get.FILE_CODE COMMIT_ID'.
+   
+   If you implement any other file types, save the commit and get
+   functions in the propper locations.
+
+     Any commit function should take a  filename   as an argument and
+     output the according commit id to stdout. stderr should be used
+     for all messages.
+
+     Any  get   function should take the commit id as an argument and
+     uses stdout only if verbose, or to report errors.
+
+   To summarize, the modules are separate programs and communicate via
+   pipes, which is generally considered bad-design, and libraries
+   should be used instead. I deliberatly broke this because:
+
+    1. incompatible licences can be used for different modules
+    2. modules can be added/removed on the fly
+    3. one can use any language to write new modules, without
+       having to worry about bindings`$(libexecdir)/$(rvs)
+
+  $$libdir$$/lib/
+   THIS WAS WRITTEN FOR rvs 0.6.2
+   THIS PORTION OF THE CODE IS BEING REVISED IN rvs 0.6.3
+
+   I have created two 'libraries' for use by rvs components. They
+   provide several functions that can be accessed by shell script by 
+   using the code:
+   	source "`rvs -d`/lib/stdio"
+   or
+   	source "`rvs -d`/lib/rvsdb"
+   (`rvs -d' returns $$libdir$$)
+   stdio provides several functions for printing messages:
+   	verbose MESSAGE
+   	   print MESSAGE to stdout only if $verbose is set to '-v'
+   	out MESSAGE
+   	   print MESSAGE to stdout if $verbose isn't set to '-q'
+   	warn MESSAGE
+   	   print "rvs: MESSAGE" to stderr
+   	error MESSAGE
+   	   print "rvs: MESSAGE" and a quick message about `rvs --help'
+   	   (hinting at user error) to stderr, then exit with error
+   	fatal MESSAGE
+   	   For internal error. Print "rvs: MESSAGE" to stderr and exit
+   	   with error
+   	version
+   	   print the version information and exit with success
+   
+   rvsdb provides several functions and variables for dealing with the
+   rvs database:
+   	getid FILE
+   	   returns what the id of a given file would be if it were in
+   	   the database. This is used to know where to put files when
+   	   commiting them. In 0.5.8-0.6.3 this is just the sha1sum of
+   	   the file
+   	NOTE: the "log*" functions aren't very stable or developed
+   	loginit FILE
+   	   initialize an rvs log at FILE. These logs are used for
+   	   metafiles, directory listings, and (probably) eventually
+   	   checkout logs
+   	lograw LOG
+   	   prepare LOG for reading, and write the output to stdout (to
+   	   pipe into another function). This is mostly for internal
+   	   use by rvsdb
+   	logread LOG VAR
+   	   read variable VAR from the logfile LOG
+   	logwrite LOG VAR VAL
+   	   set variable VAR to VAL in the logfile LOG
+   	logfind LOG VAL
+   	   return all the names of variables in logfile LOG who have
+   	   the value VAL
+
+  the database (.rvs/*)
+  
+   So, what are all these files doing in this database? The scheme is
+   fairly simple. In the `.rvs' directory there is 1 directory, the
+   `files' directory. There used to be a folder for tempfiles (0.5.8-
+   0.6.2), but no more (0.6.3+). If you need a tempfile, just run:
+   	FILENAME=`tempfile`
+   The `files' directory is where all the data is kept.
+   
+   When any file is commited, whether it be a regular file, a
+   directory, a link, or any other type of file, 2 file are created in
+   `.rvs/files', the "raw-file" and the "meta-file". When we speek of
+   file IDs, we mean the filename of the corresponding file in
+   `.rvs/files' in rvs 0.5.8-0.6.3 this is just the sha1sum of the
+   file. The meta-file stores everything not part of the file itself;
+   the filename, file-type, author, copyright owner, file permissions,
+   timestamps, etc, and the ID of the corresponding raw-file. In the
+   case of an regular file, the raw-file contains the file itself. For
+   directories, it contains pointers to each file inside the
+   directory.
+   
+   $$libdir$$/commit calls $$libdir$$/commit.FILETYPE to generate the
+   raw-file, but generates the meta-file itself (in `.rvs/tmp', then
+   calls commit.f to commit the meta-file). It then returns the ID of
+   the meta-file. Therefore, the user never deals with the IDs of
+   raw-files, and doesn't need to. The metafiles contain pointers to
+   the corresponding raw-files.
+   
+   To keep things modular, commit.f is the ONLY thing that should
+   actually put files in `.rvs/files', and get.f the only thing that
+   should get them. Everything else should call them.
+   
+   The repo and init are the ONLY things that should have `.rvs'
+   hardcoded into them. If the repository directory is needed, then
+   use `rvs repo'. Again, in the core, these should only be the .f
+   functions, however, it will be useful to plugins.
+   
+   Why do we have the `files' directory, why don't we just put
+   everything in `.rvs'? This way:
+    * There is a spot to put user data, when we get around to writing
+      it
+
+
+  final thoughts
+
+   I have set up bazaar repository at Launchpad:
+   	https://launchpad.net/rvs
+   Only until rvs becomes self-hosting.
+
+   If anyone needs any help, let me know, either via email, or via
+   Launchpad, I'll be happy to help/would love to have your help!

+//////////////////////////////////////////////////////////////////////
+                               rvs 0.8c r54
+	retroactive versioning system
+	          a versioning system that allows you to check
+	            in commit 2 before commit 1
+//////////////////////////////////////////////////////////////////////
+
+introduction
+
+   rvs is about being able to go back and edit *anything* that has
+   already been committed. Yes, some other SCMs do this, but fuck
+   things proper if someone else has a copy of the old version.
+
+   Why would you want to do this? Take for example the Bazaar
+   repository rvs is hosted on: It starts at 0.6.0, what if I later
+   want to import 0.0.0 - 0.5.10? Or if I'm trying to construct a
+   history of BSD, and import all the BSDs I can find, such as
+   1,3,4, then latter find 2?
+
+system requirements
+
+   Pretty much any *nix system should be able to run rvs. If you
+   need to use a shell other than /bin/sh, run ./configure with
+   the --SHELL=YOUR_SHELL option. rvs is not designed for Windows,
+   but should be able to run in bash if you have some *nix pack
+   installed.
+
+   To my knowledge, this is the absolute requirements (all but the
+   shell need to be in your PATH):
+     * a POSIX shell (tested with dash, and GNU BASH)
+     * cat      (included in GNU Core Utils)
+     * cp       (included in GNU Core Utils)
+     * cut      (included in GNU Core Utils)
+     * echo     (included in GNU Core Utils)
+     * mkdir    (included in GNU Core Utils)
+     * rm       (included in GNU Core Utils)
+     * sed      (included in GNU Core Utils)
+     * sha1sum  (included in GNU Core Utils)
+     * tempfile (included in GNU Core Utils)
+     * tr       (included in GNU Core Utils)
+
+building
+
+   rvs doesn't exactly use the GNU build system, but acts much like
+   it does. To build rvs with default configuration, simply run:
+   	$ ./configure
+   	$ make
+   	# make install
+
+   It's generally considered good practice to build in another
+   directory than the source directory. If you would still like to do
+   this, it can be done in rvs-0.6.1 and up.
+
+  Configuration
+
+   There are several configuration variables that can be set. You can
+   modify these configuration variables by running ./configure such
+   as:
+   	$ ./configure --VAR_NAME=VALUE
+
+   The different configuration variables are as follows:
+   	name='rvs'
+   		The name of the program. Note that unlike most
+   		variables, you should NOT call this in Makefiles
+   		(`$(name)'), but use `$(rvs)'s instead.
+   	CC='gcc'
+   		The C language compiler to use.
+   	RVS='$(bindir)/$(rvs)'
+   		Where the exectuable will be. `$(rvs)' is the same as
+   		`$(name)' (see above)
+   	SHELL='/bin/sh'
+   		The shell that will be used by make, and the shell
+   		that scripts will run in. (Perhaps we should make
+   		these separate variables?)
+   	prefix='/usr/local'
+   		Standard GNU variable. Many of you will want to
+   		change this to `/usr', or `/home/USER_NAME'
+   	exec_prefix='$(prefix)'
+   		Standard GNU variable.
+   	bindir='$(exec_prefix)/bin'
+   		Standard GNU variable.
+   	sbindir='$(exec_prefix)/sbin'
+   		Standard GNU variable.
+   	libexecdir='$(exec_prefix)/libexec'
+   		Standard GNU variable.  The plugins will be installed
+   		at $(libexecdir)/$(name)
+   	srcdir=$(readlink -f `dirname "$0"`)
+   		Where the source code is.  The default value evaluates
+   		to the directory of the `configure' script.

+	the function _plugin_sh_mktemp() is an ugly hack, it exists
