i reckon it would be useful if you and Tigran Aivazian could agree on
submitting the package to ctan.  too many useful bits of tex-ery only
exist on random websites, or in mail list archives/google groups.

things submitted to ctan get catalogued, so that there's a good chance
that people wanting to use the package in the future are actually in a
position to find it moderately quickly.
