## 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 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!
