=head1 ABSTRACT

This module allows you to interface with the GNOME Virtual File System library.
It provides the means to transparently access files on all kinds of
filesystems.

=head1 DESCRIPTION

Since this module tries to stick very closely to the C API, the documentation
found at

  L<http://developer.gnome.org/doc/API/2.0/gnome-vfs-2.0/>

is the canonical reference.

In addition to that, there's also the automatically generated API
documentation: L<Gnome2::VFS::index>.

The mapping described in L<Gtk2::api> also applies to this module.

To discuss this module, ask questions and flame/praise the authors, join
gtk-perl-list@gnome.org at lists.gnome.org.

=head1 KNOWN BUGS

There are some memory leaks especially with respect to callbacks.  This mainly
affects GnomeVFSAsync as well as some parts of GnomeVFSXfer and GnomeVFSOps.
GnomeVFSMime leaks some list data.

GnomeVFSAsync is also known to crash under certain conditions when there are
many concurrent transfers.
