The cvs for tclvfs now has an initial 1.4 with radically changed
packaging setup.  I've only tested it on Windows and Linux, but it
gets through 'make test' better than before.

I'm sure this will have repercussions on some other work, especially
with 'mk4vfs' no longer a defined package.  You can simulate with:

catch {package require bogus} ; # make sure something has been loaded
package ifneeded mk4vfs [lindex [package versions vfs::mk4] end] {
    package provide mk4vfs [package require vfs::mk4]
}

Please give it a try and let me know if anything goes horribly wrong.

Thanks,
