annotate roundup/xmlrpc.py @ 4994:868db43b302a

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Remove anypy.sets_ The anypy.sets_ package module is no longer used in the roundup codebase because python v2.4 is no longer supported. The anypy VERSION has been bumped to 0.3 to reflect this removal, but the version has probably never changed when other features were added in the past so this bump may be pointless.
