+
+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.
