[darcs-users] Darcs diff without the darcs changes listing

[Ari Johnson]

Is there a way to use darcs diff without getting the list that would
be generated by darcs changes?  I am trying to automate a script which
generates a patch between two tagged versions of the repository.  The
descriptive header of the resulting patch file will be written by the
script by extracting from a customized changelog-type file within the
repository, and the darcs changes output is superfluous at best.
Thanks for any help.
