		       The Sanitization Process


Usage:

To sanitize a directory or subtree, foo:

cd foo ; /usr/unsupported/bin/Sanitize

and you should be left with source code free of any distribution
restrictions.


Configuration:

Each directory to be kept in a release should have a .Sanitize file in
cvs.  See devo/.Sanitize for a more or less self describing template.

All files should be listed in "Things-to-keep:" or "Things-to-lose:"
(or dealt with via keep_these_too and lose_these_too, see below).  If
a file is not listed, it is removed, but a warning is printed.
Directories that are kept will have Sanitize called on their own
.Sanitize files.

The "Do-first:" section of .Sanitize should be a shell script
fragment.  It will be sourced by the Sanitize shell script after
verifying that the .Sanitize file looks reasonable but before taking
any other action.  The arguments to Sanitize are passed to this
fragment so that you can take conditional action.  For an example of
its use, see devo/gcc/config/.Sanitize.

If the "Do-first:" section sets the local shell variable
"keep_these_too", the files and/or directories listed there will be
kept in addition to any files listed in "Things-to-keep:".  If it sets
"lose_these_too", those files and/or directories will be removed in
addition to any files listed in "Things-to-lose:".  For an example of
its use, see devo/gcc/config/.Sanitize.

The "Do-last:" section of .Sanitize should be a shell script fragment.
It will be sourced by Sanitize after all other action is taken for
this directory.  This section is intended to be used to strip code out
of source files.  For an example of grep'ing out specific lines, see
devo/include/.Sanitize.  For an example of sed'ing out sections of
code, see devo/gas/config/.Sanitize.

Command line options are extremely free form.  The Sanitize script
itself only knows about keep-cvs.  All arguments to Sanitize are
passed to the "Do-first:" and "Do-last:" fragments.  Feel free to add
new options as you see fit so long as you list them here.

Defined options:

keep-cvs	avoids removing CVS.adm directories.  This option is
		actually recognized and handled by the Sanitize shell
		script.

keep-cygnus	avoids removing Cygnus-only bits.
keep-v9  	avoids removing the v9 stuff.
keep-life	avoids removing the life stuff.
keep-cri	avoids removing the cray research inc changes to emacs.
keep-chill	avoids removing CHILL support.
keep-mpw	avoids removing MPW host support.
keep-gm		avoids removing GM-specific stuff.
keep-powerpc-netware	avoids removing PPC NetWare stuff.

for-intel	builds a distribution in the style that Intel likes.
for-fsf		builds a distribution in the style that the FSF likes.

test		instead of removing dirty files, cache them away in a
		.Recover directory
recover		intended to undo the effects of a "Sanitize test".
