 The `.ikiwiki` directory contains ikiwiki's internal state. Normally,
 you don't need to look in it, but here's some tips for how to do so if

+## the session database
+
+`.ikiwiki/sessions.db` is the session database. See the [[cpan CGI::Session]]
+documentation for more details.
+
+## lockfiles
+
+In case you're curious, here's what the various lock files do.
+
+* `.ikiwiki/lockfile` is the master ikiwiki lock file. Ikiwiki takes this 
+  lock before reading/writing state.
+* `.ikiwiki/commitlock` is locked as a semophore, to disable the commit hook
+  from doing anything.
+* `.ikiwiki/cgilock` is locked by the cgi wrapper, to ensure that only 
+  one ikiwiki process is run at a time to handle cgi requests.
+
+## plugin state files
+
+Some plugins create other files to store their state. 
+
+* `.ikiwiki/aggregate` is a plain text database used by the aggregate plugin
+  to record feeds and known posts.
+* `.ikiwiki/xapian/` is created by the search plugin, and contains xapian-omega
+  configuration and the xapian database.
