Reminds me of my first contact with TeX back in 1991. Having just got a PhD and a research position at the French CNRS, I asked about TeX (which I had heard mentioned by some fellow scientist, without knowing what this was) and was handed the Textures box set.

Textures came with two macro packages (apart from LaTeX): the midnight macros by Marcel van der Goot, and eplain by Karl. That's how (the eplain manual) I heard first about GNU, and was astonished to read there a criticism of Apple. I couldn't understand then how someone could be against the Mac. Now I understand (and know) a bit more.

I'm probably to blame for that. Having installed Perl/Tk and launched the tlmgr GUI, I noticed that it gave more version information than TLU (TLU back then had only showed the revision information, which I didn't really find useful).

So I asked (probably on the MacTeX list) whether it was possible to have the same information as with tlmgr. Adam asked whether tlmgr had some command-line option returning (what's now know as) the catalogue version, Norbert kindly added the option and Adam kindly used it to add the the information inside TLU.
