 GNOME VFS is the GNOME virtual file system. It is the foundation of the
 Nautilus file manager. It provides a modular architecture and ships with
 several modules that implement support for local files, http, ftp and others.
 It provides an URI-based API, a backend supporting asynchronous file
 operations, a MIME type manipulation library and other features.
 .
 This package contains unstripped shared libraries. It is provided primarily
 to provide a backtrace with names in a debugger, to make it easier to
 interpret core dumps. The libraries are installed in /usr/lib/debug and are
 automatically used by gdb.
