`help2man' generates a man page out of `--help' and `--version' output.

Usage: help2man [OPTION]... EXECUTABLE

  -n, --name=STRING         use `STRING' as the description for the NAME paragraph
  -s, --section=SECTION     use `SECTION' as the section for the man page
  -i, --include=FILE        include material from `FILE'
  -I, --opt-include=FILE    include material from `FILE' if it exists
  -o, --output=FILE         send output to `FILE'
  -N, --no-info             suppress pointer to Texinfo manual
      --alt_version_key=KEY use specified flag instead of --version
      --help                print this help, then exit
      --version             print version number, then exit

EXECUTABLE should accept `--help' and `--version' options.

The lsb_release-1.4 help2man does not accept the --help-option. With
sed '/--help-option=/d' -i pango-view/meson.build
it builds ok.

help2man is a perl script.  The one in lsb-release is quite old.  I don't think it is worth adding a whole page for installing it, but we could add an additional download to lsb-release with a newer version.


Having a new help2man version in the book sounds good. I'm not sure
if the lsb-release page is the most appropriate place to place the
download link.
