Darcs repositories back

[kpreid]

The previously-mentioned darcs repositories (which are e-aui, e-modules, factor, norsmu) have been moved to my new server at http://switchb.org/darcs/. As far as I recall, I haven't published any links to these except privately and to mailing lists, so I haven’t updated any links for the new location; but if you had the old location, now you know where to go.
