Editing: cvs2includes

#!/usr/bin/perl
#
# This script finds all CVS/Entries files in the current directory and below
# and creates a local .cvsinclude file with non-inherited rules including each
# checked-in file.  Then, use this option whenever using --cvs-exclude (-C):
#
# 	-f ': .cvsinclude'
#
# That ensures that all checked-in files/dirs are included in the transfer.
# (You could alternately put ": .cvsinclude" into an .rsync-filter file and
# use the -F option, which is easier to type.)
#
# The downside is that you need to remember to re-run cvs2includes whenever
# you add a new file to the project.
