-The three parameters are the filename to add, the name of the plugin,
-and a callback function. The callback will be called if it is appropriate
-to automatically add the file, and should then take care of creating it,
-and doing anything else it needs to (such as checking it into revision
-control). Note that the callback may not always be called. For example,
-if an automatically added file is deleted by the user, ikiwiki will avoid
-re-adding it again.
