# 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
|
|
# CVS gets an added or removed file. Maybe just run it before every copy.
