(<a href="http://fuse.sourceforge.net/">http://fuse.sourceforge.net/</a>), which allows filesystems to be implemented
as userspace processes.
</p><p>The binding tries to follow as much as possible current Haskell POSIX
interface in <a href="/usr/share/doc/ghc-doc/html/libraries/unix-2.6.0.1/System-Posix-Files.html">System.Posix.Files</a> and <a href="/usr/share/doc/ghc-doc/html/libraries/unix-2.6.0.1/System-Posix-Directory.html">System.Posix.Directory</a>.
</p><p>FUSE uses POSIX threads, so any Haskell application using this library must
be linked against a threaded runtime system (eg. using the <code>threaded</code> GHC
option).
