Afuse is an automounting file system implemented in user-space using FUSE.
Afuse currently implements the most basic functionality that can be expected by
an automounter; that is it manages a directory of virtual directories. If one
of these virtual directories is accessed and is not already automounted, afuse
will attempt to mount a filesystem onto that directory. If the mount succeeds
the requested access proceeds as normal, otherwise it will fail with an error.

The advantage of using afuse over traditional automounters is afuse runs
entirely in user-space by individual users. Thus it can take advantage of the
invoking users environment, for example allowing access to an ssh-agent for
password-less sshfs mounts, or allowing access to a graphical environment to
get user input to complete a mount such as asking for a password.
