[[!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
