+***
+
+I have a few notes on mercurial usage after trying it out for a while:
+
+1. I have been using ikiwiki's `--post-commit` option without apparent problems. I'm the only current user of my wiki, though.
+
+1. The `ikiwiki.setup` file included in ikiwiki works with mercurial's `hgserve`, which is not the preferred solution. Mercurial's `hgwebdir.cgi` is more flexible and doesn't require running a server. I have this in my .setup file:
+
+        # Mercurial stuff.
+        rcs => "mercurial",
+        historyurl => "http://localhost/cgi-bin/hgwebdir.cgi/ikiwiki/log/tip/\[[file]]",
+        diffurl => "http://localhost/cgi-bin/hgwebdir.cgi/ikiwiki/diff/tip/\[[file]]",
+
+1. I have noticed that running `ikiwiki` after a change to the wiki adds files to a directory called `recentchanges` under `$srcdir`. I don't understand why such files are needed; worse, they are not added to mercurial's list of tracked files, so they polute the output of `hg log`. Is this a bug? Should mercurial's commit hook be modified to add these files before the commit?
+
+--buo
+
+> No, those files should not be added to revision control. --[[Joey]]
+
+>> OK. I see two problems:
+
+>> 1. If I clone my wiki, I won't get an exact copy of it: I will lose the recentchanges history. This could be an acceptable limitation but IMO this should be documented.
+
+>>> The history is stored in mercurial. How will it be lost?
+
+>> 2. The output of `hg status` is polluted. This could be solved trivially by adding a line containing `recentchanges` to `.hgignore`. Another alternative would be to store the `recentchanges` directory inside `$srdcir/.ikiwiki`.
+
+>> I think the ideal solution would be to build `$destdir/recentchanges/*` directly from the output of `hg log`. --[[buo]]
+
+>>>> That would be 100 times as slow, so I chose not to do that. --[[Joey]]
