[darcs-users] A darcsum-diff question and a darcs diff question (and a bug?)

[Dominic Steinitz]

Hi,

I'm trying to get the difference between 2 versions of a file. Ideally I
would like to use darcsum and get the result in an emacs buffer. I
haven't been able to coax darcsum-diff into doing this so I resorted to
the command line. But I get a darcs failure.

1. Ideally I would like to do darcs diff using darcsum. Any help would
be appreciated.

2. What syntax should I use to get a diff of two versions at the command
line?

Thanks, Dominic.

The two versions I am trying to diff are identified by these patches
