 * CVS multi-directory commits happen separately; the post-commit hook sees only the first directory's changes in time for [[recentchanges|plugins/recentchanges]]. The next run of `ikiwiki --setup` will correctly re-render such a recentchanges entry. It might be possible to solve this problem with scripts like `commit_prep` and `log_accum` from CVS contrib.
