The main reason is a kind of silly one:
xz-man.pot contains strings from all man pages in XZ Utils.
The man pages of xzdiff, xzgrep, and xzmore were under GPLv2
and the rest under 0BSD. Thus xz-man.pot contained strings
under two licences. po4a creates the translated man pages
from the combined 0BSD+GPLv2 xz-man.pot.
I haven't liked this mixing in xz-man.pot but the
Translation Project requires that all man pages must be
in the same .pot file. So a separate xz-man-gpl.pot
wasn't an option.
Since these man pages are short, rewriting them was quick enough.
Now xz-man.pot is entirely under 0BSD and marking the per-file
licenses is simpler.
As a bonus, some wording hopefully is now slightly better
although it's perhaps a matter of taste.
NOTE: In xzgrep.1, the EXIT STATUS section was written by me
in the commit d796b6d7fd so that's
why that section could be taken as is from the old xzgrep.1.
Lots of content was updated on the xz man page.
Technical improvements:
- Start a new sentence on a new line.
- Use fairly short lines.
- Use constant-width font for examples (where supported).
- Some minor cleanups.
Thanks to Jonathan Nieder for some language fixes.
the latest versions found from gzip CVS repository.
configure will try to find a POSIX shell to be used by
the scripts. This should ease portability on systems
which have pre-POSIX /bin/sh.
xzgrep and xzdiff support .xz, .lzma, .gz, and .bz2 files.
xzmore and xzless support only .xz and .lzma files.
The name of the xz executable used in these scripts is
now correct even if --program-transform-name has been used.
