76 This module allows you to interface with the GNOME Virtual File System
77 library. It provides the means to transparently access files on all
78 kinds of filesystems.
79
81 Since this module tries to stick very closely to the C API, the
82 documentation found at
83
84 L<http://developer.gnome.org/doc/API/2.0/gnome-vfs-2.0/>
85
86 is the canonical reference.
87
88 In addition to that, there's also the automatically generated API
89 documentation: Gnome2::VFS::index.
90
91 The mapping described in Gtk2::api also applies to this module.
92
93 To discuss this module, ask questions and flame/praise the authors,
94 join gtk-perl-list@gnome.org at lists.gnome.org.
95
97 There are some memory leaks especially with respect to callbacks. This
98 mainly affects GnomeVFSAsync as well as some parts of GnomeVFSXfer and
99 GnomeVFSOps. GnomeVFSMime leaks some list data.
100
101 GnomeVFSAsync is also known to crash under certain conditions when
102 there are many concurrent transfers.
