0006 # Initial author: Dirk Mueller
0007 # Support for multiple command-line arguments, handling of patch rejects: David Faure
0008 # Ported to SVN: Till Gerken
0009 # Options and quote-safety: Matthew Woehlke

0011 # This isn't the most sophisticated script ever, and might break. It needs to be
0012 # used from within the repository so that it can guess the remote URL correctly.
