# .Sanitize for devo/sim/d10v.
# Each directory to survive its 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 directory.
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.
