If nobody complains, let's run with it.

Ah, I just basically copy/pasted from <http://wiki.tcl.tk/1624> :

"To access the env array within a Tcl proc, one needs to tell the proc that env is a global array. There are two ways to do this.

    $::env(PATH)
    global env ; puts $env(PATH) can alternatively used to identify that the variable is
    globally available; however, you have to remember to use the global command
    in EVERY proc that you need to use env. Using the $::env notation is shorter."

Since this is global code anyway (not within a proc) $env should be fine (and is the
style used elsewhere).  Go ahead and make that change.

It's true, most of my tcl foo is web search based.  :-)

Looks fine to me.  Thanks!
