### `template($;@)`
-Creates and returns a [[!cpan HTML::Template]] object. The first parameter
-is the name of the file in the template directory. The optional remaining
+Creates and returns a [[!cpan HTML::Template]] object. (In a list context,
+returns the parameters needed to construct the obhect.)
+
+The first parameter is the name of the template file. The optional remaining
parameters are passed to `HTML::Template->new`.
+Normally, the template file is first looked for in the templates/ subdirectory
+of the srcdir. Failing that, it is looked for in the templatedir.
+
+Wiki pages can be used as templates. This should be done only for templates
+which it is safe to let wiki users edit. Enable it by passing a filename
+with no ".tmpl" extension. Template pages are normally looked for in
+the templates/ directory. If the page name starts with "/", a page
+elsewhere in the wiki can be used.
+
+### `template_depends($$;@)`
+
+Use this instead of `template()` if the content of a template is being
+included into a page. This causes the page to depend on the template,
+so it will be updated if the template is modified.
+
+Like `template()`, except the second parameter is the page.
+
### `htmlpage($)`
Passed a page name, returns the base name that will be used for a the html
If the directory name is not absolute, ikiwiki will assume it is in
the parent directory of the configured underlaydir.
-### `displaytime($;$)`
+### `displaytime($;$$)`
Given a time, formats it for display.
The optional second parameter is a strftime format to use to format the
time.
+If the third parameter is true, this is the publication time of a page.
+(Ie, set the html5 pubdate attribute.)

### `gettext`
This is the standard gettext function, although slightly optimised.
### `add_autofile($$$)`
-Sometimes you may want to add a file to the `srcdir`. For example,
-[[plugins/tag]] pages can be automatically created as needed. This function
-can be used to do that.

-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.
