 Using this extension, the editor Alphatk can actually auto-mount, view and

+None of the vfs's included are 100% complete or optimal yet, so if only for

+Some of the provided vfs's require the Memchan extension for any operation 
+which involves opening files.

+The vfs's currently available are:

+--------+-----------------------------------------------------------------
+vfs     |  mount command                       
+--------+-----------------------------------------------------------------
+zip     |  vfs::zip::Mount my.zip local
+ftp     |  vfs::ftp::Mount ftp://user:pass@ftp.foo.com/dir/name/ local
+mk4     |  vfs::mk4::Mount myMk4database local
+test    |  vfs::test::Mount ...
+tclproc |  vfs::tclproc::Mount ::tcl local
+--------+-----------------------------------------------------------------
+
+For file-systems which make use of a local file (e.g. mounting zip or mk4
+archives), it is often most simple to have 'local' be the same name as 
+the archive itself.  The result of this is that Tcl will then see the
+archive as a directory, rather than a file.  Otherwise you might wish
+to create a dummy file/directory called 'local' before mounting.
