+There are many parameters you can use with the `inline`
+directive. These are the commonly used ones:
 
 * `pages` - A [[PageSpec]] of the pages to inline.
 * `show` - Specify the maximum number of matching pages to inline.
   Default is 10, unless archiving, when the default is to show all.
   Set to 0 to show all matching pages.

+* `description` - Sets the description of the rss feed if one is generated.
+  Defaults to the name of the wiki.
 * `skip` - Specify a number of pages to skip displaying. Can be useful
   to produce a feed that only shows archived pages.
+* `postform` - Set to "yes" to enable a form to post new pages to a
+  [[blog]].
+* `postformtext` - Set to specify text that is displayed in a postform.
+* `rootpage` - Enable the postform, and allows controling where
+  newly posted pages should go, by specifiying the page that
+  they should be a [[SubPage]] of.

+Here are some less often needed parameters:

+* `actions` - If set to "yes" add links to the bottom of the inlined pages 
+  for editing and discussion (if they would be shown at the top of the page
+  itself).
 * `rss` - controls generation of an rss feed. If the wiki is configured to
   generate rss feeds by default, set to "no" to disable. If the wiki is
   configured to `allowrss`, set to "yes" to enable.

+
+If attachments are enabled, the wiki admin can control what types of
+attachments will be accepted, by entering a [[ikiwiki/PageSpec]] in the
+"Allowed Attachments" field of their preferences page.
+
+For example, to limit arbitrary files to 50 kilobytes, but allow
+larger mp3 files to be uploaded by joey into a specific directory, and
+check all attachments for virii, something like this could be used:
+  
+	virusfree() and ((user(joey) and podcast/*.mp3 and mimetype(audio/mpeg) and maxsize(15mb)) or (!ispage() and maxsize(50kb)))
+
+The regular [[ikiwiki/PageSpec]] syntax is expanded with thw following
+additional tests:
+
+* maxsize(size)
+
+  Tests whether the attachment is no larger than the specified size.
+  The size defaults to being in bytes, but "kb", "mb", "gb" etc can be
+  used to specify the units.
+  
+* minsize(size)
+
+  Tests whether the attachment is no smaller than the specified size.
+
+* ispage()
+
+  Tests whether the attachment will be treated by ikiwiki as a wiki page.
+  (Ie, if it has an extension of ".mdwn", or of any other enabled page
+  format).
+
+  So, if you don't want to allow wiki pages to be uploaded as attachments,
+  use `!ispage()` ; if you only want to allow wiki pages to be uploaded
+  as attachments, use `ispage()`.
+
+* user(username)
+
+  Tests whether the attachment is being uploaded by a user with the
+  specified username. If openid is enabled, an openid can also be put here.
+
+* ip(address)
+
+  Tests whether the attacment is being uploaded from the specified IP
+  address.
+
+* mimetype(foo/bar)
+
+  This checks the MIME type of the attachment. You can include a glob
+  in the type, for example `mimetype(image/*)`.
+
+* virusfree()
+
+  Checks the attachment with an antiviral program.
