# .Sanitize for devo/sim/ppc.
|
||||
|
||||
# Each directory to survive it's way into a release will need a file
|
||||
# like this one called "./.Sanitize". All keyword lines must exist,
|
||||
# and must exist in the order specified by this file. Each directory
|
||||
# in the tree will be processed, top down, in the following order.
|
||||
|
||||
# Hash started lines like this one are comments and will be deleted
|
||||
# before anything else is done. Blank lines will also be squashed
|
||||
# out.
|
||||
|
||||
# The lines between the "Do-first:" line and the "Things-to-keep:"
|
||||
# line are executed as a /bin/sh shell script before anything else is
|
||||
# done in this
|
||||
|
||||
Do-first:
|
||||
|
||||
# All files listed between the "Things-to-keep:" line and the
|
||||
# "Files-to-sed:" line will be kept. All other files will be removed.
|
||||
# Directories listed in this section will have their own Sanitize
|
||||
# called. Directories not listed will be removed in their entirety
|
||||
# with rm -rf.
