Catacomb is a WebDAV repository module for use
with the Apache WebDAV module, mod_dav. Apache
mod_dav parses WebDAV and DeltaV protocol requests
into operations on a repository providing
persistent storage of resources and their
properties. The default repository for mod_dav is
provided by a separate module, mod_dav_fs, which
stores resource bodies as files in the filesystem,
and stores properties in a (G)DBM database. It
could be used for server side searching and
versioning of files over the HTTP protocol.
