If you really need to, you can use [[!wikipedia desc="CVS" Concurrent
Versions System]] with ikiwiki.

### Usage
7. Install [[!cpan File::chdir]], [[!cpan File::ReadBackwards]],
   [cvsps](http://www.cobite.com/cvsps/)
   (note: probably not [cvsps3](http://www.catb.org/~esr/cvsps/)), and
   [cvsweb](http://www.freebsd.org/projects/cvsweb.html) or the like.
7. Adjust CVS-related parameters in your setup file.

Consider creating `$HOME/.cvsrc` if you don't have one already; the
plugin doesn't need it, but you yourself might. Here's a good
general-purpose one:

    cvs -q
    checkout -P
    update -dP
    diff -u
    rdiff -u

### Implementation details
* [[ikiwiki-makerepo]]:
    * creates a repository,
    * imports `$SRCDIR` into top-level module `ikiwiki` (vendor tag
      IKIWIKI, release tag PRE_CVS),
    * configures the post-commit hook in `CVSROOT/loginfo`.

### To do
* Expand test coverage and fix bugs.
* Have `ikiwiki-makerepo` set up NetBSD-like `log_accum` and
  `commit_prep` scripts that coalesce commits into changesets. Reasons:
    7. Obviates the need to scrape the repo's complete history to
       determine the last N changesets. (Repositories without such
       records can fall back on the `cvsps` and `File::ReadBackwards`
       code.)
    7. Arranges for ikiwiki to be run once per changeset, rather
       than CVS's once per committed file (!), which is a waste at
       best and bug-inducing at worst. (Currently, on multi-directory
       commits, only the first directory's changes get mentioned
       in [[recentchanges|plugins/recentchanges]].)
* Perhaps prevent web edits from attempting to create `.../CVS/foo.mdwn`
  (and `.../cvs/foo.mdwn` on case-insensitive filesystems); thanks
  to the CVS metadata directory, the attempt will fail anyway (and
  much more confusingly) if we don't.
* Do a writeup for [[rcs/details]].
