Honestly, Adam's run-through was so close to being exhaustive and
definitive as to be IMO sort of breathtaking. And thus appreciated by this
correspondent.

He didn't cover the antique Compress utility that gave us the .Z prefix,
either, but c'mon. Computing history is littered with obsolete
compression and archiving formats. I remember during the years when I
was a BBS sysop / owner / operator in the 1980s and early 1990s, the
DOS-oriented computing world went through a menagerie of such things:
arc, pkzip, arj, and many others I'm trying hard to forget.

Adam's argument for xz is IMO very compelling except for us poor
bastards who choose to make online content including non-software
content easily accessible to users of unfortunate operating systems
(which would fall under Adam's 'compatibility' wording).
