# This script can be used as an rsync command-line filter that strips a single
# trailing slash from each arg.  That treats "src/" the same as "src", thus
# you need to use "src/." or "src//" for just the contents of the "src" dir.
# (Note that command-line dir-excludes would need to use "excl//" too.)
#
# To use this, name it something like "rs", put it somewhere in your path, and
# then use "rs" in place of "rsync" when you are typing your copy commands.
