 This plugin provides a [[ikiwiki/directive/calendar]] [[ikiwiki/directive]].
 The directive displays a calendar, similar to the typical calendars shown on
-some blogs.
+some blogs. 
 
-Since ikiwiki is a wiki compiler, to keep the calendar up-to-date,
-wikis that include it need to be periodically refreshed, typically by cron
-at midnight. Example crontab:
-
-	0 0 * * * ikiwiki -setup ~/ikiwiki.setup -refresh
+The [[ikiwiki-calendar]] command is used to keep the calendar up-to-date.

+[[!template id=plugin name=groupfile core=0 author="[[Jogo]]"]]
+
+This plugin add a `group(groupname)` function to [[ikiwiki/PageSpec]], which is true
+only if the actual user is member of the group named `groupname`.
+
+Groups membership are read from a file. The syntax of this file is very close to
+usual `/etc/passwd` Unix file : the group's name, followed by a colon, followed by
+a coma separated list of user's names. For exemple :
+
+    dev:toto,foo
+    i18n:zorba
