ok, here's a thought: posit: if a work is a product of the us government, it is in the public domain.
thus, anybody can reuse and relicence it in any way one wishes. for instance, you could grab any us government produced software and gpl it (or whatever lese you like) for a debian package. if i'm wrong here, and it has to stay in pd or some such, then a copyright file with "this work is a product of the us government, and as such is not copyrighted; anyone may use, modify, and distribute it in any way." should suffice. even a disclaimer of warranty if you want, in particular as ppl might (won't, but in theory might) try to weasel cash from you as packager / maintainer which could (again, won't, but could) be construed to imply a warranty. --p.
