1 Goal: Web interface to allow reverting of changes.
5 At least at first, it will be exposed via the recentchanges
6 page, with revert icons next to each change. We may want a dynamic
7 per-page interface that goes back more than 100 changes later.
11 * No support for resolving conflicts in reverts; such a revert would just
13 * No support for reset-to-this-point; initially the interface would only
14 revert a single commit, and if a bunch needed to go, the user would have
15 to drive that one at a time.
19 * `rcs_revert` hook that takes a revision to revert.
20 * CGI: `do=revert&rev=foo`
21 * recentchanges plugin adds above to recentchanges page
22 * prompt user to confirm (to avoid spiders doing reverts),
23 check that user is allowed to make the change, commit reversion,
26 Peter Gammie has done an initial implementation of the above.

65 >>> I agree, but have not figured out a way to make a hook work yet.

70 >>> I have made my own revert branch and put a few^Wseveral fixes in there.
71 >>> All merged to master now! --[[Joey]]
