    (straightforward no-sell licence.  definitely impossible to put this in
    tex live, which can sometimes find itself being sold.)

Evidently colortab was written by Timothy van Zandt, who, as far as I
know, is uncontactable.  So I see no hope for that.

According to Robin's catalogue entry, a possible answer is to use
colortbl or xcolor.

I asked Mats Dahlgren if he would be willing to relax his license.
