edittemplate directive is supplied by the edittemplate plugin.
This directive allows registering template pages, that provide default content for new pages created using the web frontend. To register a template, insert a template directive on some other page.
[[!edittemplate template="bugtemplate" match="bugs/*"]]
A recommended place to put the directive is on the parent page of the pages that will be created using the template. So the above example would be put on the bugs page. (Do not put the directive on the template page itself.)
In the above example, the page named "bugtemplate" is registered as a template to be used when any page named "bugs/*" is created. To avoid the directive displaying a note about the template being registered, add "silent=yes".
Often the template page contains a simple skeleton for a particular type of page. For the bug report pages in the above example, it might look something like:
