-To provide a way to combat these abuses, the wiki admin can specify a
-[[ikiwiki/PageSpec]] on their preferences page, to control what types of
-attachments can be uploaded, and by whom. The regular [[ikiwiki/PageSpec]]
-syntax is expanded with additional tests.
-
-For example, to limit arbitrary files to 50 kilobytes, but allow
-larger mp3 files to be uploaded by joey, a test like this could be
-used:
-
- (user(joey) and *.mp3 and mimetype(audio/mpeg) and maxsize(15mb)) or (!ispage() and maxsize(50kb))
-
-The following additional tests are available:
-
-* 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)
-
- If the [[cpan File::MimeInfo::Magic]] perl module is installed, this
- allows checking the mime type of the attachment. You can include a glob
- in the type, for example `mimetype(image/*)`.
+If you enable this plugin, be sure to lock it down, via the
+`allowed_attachments` setup file option. This is a special
+[[enhanced_PageSpec|ikiwiki/pagespec/attachment]] using tests provided by
+the [[filecheck]] plugin. That plugin will be automatically enabled when
+this plugin is enabled.
