The function is passed named parameters: "page" and "content", and
should return the formatted content.
+### build_affected
+
+ hook(type => "build_affected", id => "foo", call => \&build_affected);
+
+This hook is called after the directly changed pages have been built,
+and can cause extra pages to be built. If links and backlinks were provided
+by a plugin, this would be where that plugin would rebuild pages whose
+backlinks have changed, for instance. The [[trail]] plugin uses this hook
+to rebuild pages whose next or previous page has changed.
+
+The function should currently ignore its parameters. It returns a list with
+an even number of items (a hash in list context), where the first item of
+each pair is a page name to be rebuilt (if it was not already rebuilt), and
+the second is a log message resembling
+`building plugins/write because the phase of the moon has changed`.

### cgi
hook(type => "cgi", id => "foo", call => \&cgi);
* `description` is a short description of the option.
* `link` is a link to further information about the option. This can either
be a [[ikiwiki/WikiLink]], or an url.
+* `htmldescription` is displayed instead of the description by websetup.
* `advanced` can be set to true if the option is more suitable for advanced
users.
* `safe` should be false if the option should not be displayed in unsafe
second. The first parameter can be either a page name, or some other
destination file, as registered by `will_render`.
-If the second parameter is `undef` (or not specified), the URL will be
+Provide a second parameter whenever possible, since this leads to better
+behaviour for the [[plugins/po]] plugin and `file:///` URLs.
+
+If the second parameter is not specified (or `undef`), the URL will be
valid from any page on the wiki, or from the CGI; if possible it'll
be a path starting with `/`, but an absolute URL will be used if
the wiki and the CGI are on different domains.
-If the third parameter is passed and is true, an absolute url will be
-constructed instead of the default relative url.
+If the third parameter is passed and is true, the url will be a fully
+absolute url. This is useful when generating an url to publish elsewhere.
### `newpagefile($$)`
Remove a file. The filename is relative to the root of the srcdir.
Note that this should not commit the removal, it should only prepare for it
