An example filter script to maintain .cvsinclude files.

support/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'
+#
+# (You could alternately put ": .cvsinclude" into an .rsync-filter file and
+# use the -F option, which is easier to type.)
+#
+# That ensures that all checked-in files/dirs are included in the transfer.
+#
+# The downside is that you need to remember to re-run cvs2includes whenever
+# You add a new file to the project.
