That looks better.  A pity that alphabetical order doesn't well reflect
popularity order in any way.

It goes something like this:

    set platform unknown
    if {[info exists ::env(HTTP_USER_AGENT)]} {
        # We can't do this for cached pages - or do it in js
        switch -glob $::env(HTTP_USER_AGENT) {
            *Windows*    { set platform Windows }
            *Macintosh*  { set platform "Mac OS X" }
            *Linux*      { set platform Linux }
            *SunOS* - *Solaris* { set platform Solaris }
        }
	...

but then what you do with $platform is up to you.  I've not drilled down to
how you might differentiate OS subtypes, if possible.  I didn't find anything
online that is complete about what user agents you might expect.
