This plugin allows files to be uploaded to the wiki over the web.

For each page `foo`, files in the subdirectory `foo/` are treated as attachments of that page. Attachments can be uploaded and managed as part of the interface for editing a page.

Warning: Do not enable this plugin on publically editable wikis, unless you take care to lock down the types and sizes of files that can be uploaded. Bear in mind that if you let anyone upload a particular kind of file ("*.mp3" files, say), then someone can abuse your wiki in at least three ways:

1. By uploading many mp3 files, wasting your disk space.
2. By uploading mp3 files that attempt to exploit security holes in web browsers or other players.
3. By uploading files that claim to be mp3 files, but are really some other kind of file. Some web browsers may display a `foo.mp3` that contains html as a web page; including running any malicious javascript embedded in that page.

If you enable this plugin, be sure to lock it down, via the `allowed_attachments` setup file option. This is a special enhanced PageSpec using tests provided by the filecheck plugin. That plugin will be automatically enabled when this plugin is enabled.
