 This plugin allows ikiwiki to use [[!wikipedia desc="CVS" Concurrent Versions System]] as an [[rcs]].
 
-* Diffs are against [[3.14159|news/version_3.14159]]. `cvs.pm` started life as a copy of `svn.pm`.
-* `IkiWiki.pm` avoids copying CVS metadata into `$DESTDIR`.
-* [[ikiwiki-makerepo]]:
- * creates a repository,
- * imports `$SRCDIR` into top-level module `ikiwiki` (vendor tag IKIWIKI, release tag PRE_CVS),
- * creates a small post-commit wrapper to prevent `cvs add <directory>` from being seen by ikiwiki's [[post-commit]] hook,
- * configures the wrapper itself as a post-commit hook in `CVSROOT/loginfo`.
-* [`cvsps`](http://www.cobite.com/cvsps/) is required (`rcs_recentchanges()` and `rcs_diff()` need it to work).
-* 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.
-* Due to the name of CVS's metadata directories, it's impossible to create `.../CVS/foo.mdwn`. On case-insensitive filesystems it's also impossible to create `.../cvs/foo.mdwn`.
-* No testing or special-casing has been done with [[attachments|plugins/attachment]], but they'll probably need `cvs add -kb`.
+### Usage
+7. Install [cvsps](http://www.cobite.com/cvsps/), [[!cpan
+File::ReadBackwards]], and
+[cvsweb](http://www.freebsd.org/projects/cvsweb.html) or the like.
+7. Adjust CVS-related parameters in your setup file.
 
-Having a `$HOME/.cvsrc` isn't necessary. Sure does make using CVS more livable, though. Here's a good general-purpose one:

-Not knowing how the tests get set up, I blindly attempted to add subversion-like tests to `t/file_pruned.t`. They fail. But the plugin definitely works. :-)
+### Implementation details
+* `cvs.pm` started life as a copy of [[3.14159|news/version_3.14159]]'s `svn.pm`.
+* `IkiWiki.pm:wiki_file_prune_regexps` avoids copying CVS metadata
+into `$DESTDIR`.
+* `IkiWiki/Wrapper.pm` avoids calling ikiwiki from post-commit if it's a
+directory being `cvs add`ed (this check is only compiled into the wrapper
+iff the configured VCS is "cvs").
+* [[ikiwiki-makerepo]]:
+ * creates a repository,
+ * imports `$SRCDIR` into top-level module `ikiwiki` (vendor tag IKIWIKI, release tag PRE_CVS),
+ * configures the post-commit hook in `CVSROOT/loginfo`.
+* 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 should be possible to solve this problem with NetBSD's `commit_prep` and `log_accum` scripts (see below).
 
-### Code
-* [`cvs.pm`](http://www.netbsd.org/~schmonz/ikiwiki-cvs/cvs.pm)
-* [`cvs-IkiWiki.pm.diff`](http://www.netbsd.org/~schmonz/ikiwiki-cvs/cvs-IkiWiki.pm.diff)
-* [`cvs-ikiwiki-makerepo.diff`](http://www.netbsd.org/~schmonz/ikiwiki-cvs/cvs-ikiwiki-makerepo.diff)
-* [`cvs-t-file_pruned.t.diff`](http://www.netbsd.org/~schmonz/ikiwiki-cvs/cvs-t-file_pruned.t.diff)
+### To do
+* Add automated tests. (Blindly adding svn-like tests to `t/file_pruned.t` doesn't do the trick.)
+* Instead of resource-intensively scraping changesets with `cvsps`, have `ikiwiki-makerepo` set up NetBSD-like `log_accum` and `commit_prep` scripts that coalesce and keep records of commits. `cvsps` can be used as a fallback for repositories without such records.
+* 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.
