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.
The default action is to remove all files and directories not
explicitly listed in the .Sanitize file as being "Things-to-keep:".
Directories that are kept will have Sanitize called on their own
.Sanitize files.
For other than default action, there are three hooks.
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
it's 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:". For an
example of it's 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-v9 avoids removing the v9 stuff.
keep-life avoids removing the life stuff.
keep-cri avoids removing the cray research inc changes to emacs.
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".
