New Revision: 2384

Added:
   trunk/scripts/dpatchify.rb
Log:
# dpatchify.rb - add dpatch headers to a patch (or group of patches)
# This will (when supplied w/ foo.patch) create a file called foo.dpatch,
# that contains a dpatch header.  It assumes a standard bitkeeper header
# will be in the original patch file, and fills in the dpatch header info
# from that.  Useful for instantly dpatch-izing large sets of bk backports.
