Subject: [bug#73795] [PATCH] Add support for the bzip3 compression tool to automake.
Date: Thu, 13 Mar 2025 15:42:35 -0600

Karl

P.S. I humbly suggest explicitly stating in the man page that no envvars
are read, since that is a departure from the other common compression
programs.

Analogous changes throughout.
