   3 # This script finds all CVS/Entries files in the current directory and below
   4 # and creates a local .cvsinclude file with non-inherited rules including each
   5 # checked-in file.  Then, use this option whenever using --cvs-exclude (-C):
   6 #
   7 #       -f ': .cvsinclude'
   8 #
   9 # That ensures that all checked-in files/dirs are included in the transfer.
  10 # (You could alternately put ": .cvsinclude" into an .rsync-filter file and
  11 # use the -F option, which is easier to type.)
  12 #
  13 # The downside is that you need to remember to re-run cvs2includes whenever
  14 # you add a new file to the project.
