DESCRIPTION

       The  ::vfs  package  includes  a  library  of Tcl code, implementing a number of different
       virtual filesystems.  Each of these exists as its own package, and can be accessed through
       package  require  vfs::NAME.   The whole set of virtual filesystems is known informally as
       'vfslib'

SUPPORTED VFS TYPES

       The current supported types are ftp, tar, http, zip, mk4, ns, webdav.  In  addition  there
       is  the  ability  to  mount  any 'urltype' as a new volume, provided an appropriate vfs is
       supported.  This means that you can treat 'ftp://', 'http://' and 'file://' urls as files.
       To do this, simply evaluate the command

       vfs::urltype::Mount ftp

       for  instance.   Any  access  inside the new volume will result in an attempt to require a
       package through 'package require vfs::${type}', which must therefore exist, or errors will
       be thrown.

LIMITATIONS

       Most  of  the vfs types listed above have not been very well debugged as yet.  Please test
       them!
