# The manual page for each executable is generated from its own --help output,
# so that an option added to the program turns up in the page without anyone
# having to write it down a second time.  Everything help2man cannot know, the
# prose around the option list, lives in the matching .h2m include file.
#
# The COPYRIGHT and AUTHOR sections are made out of --version, so nothing here
# has to know the version or repeat the licence.
#
# --source is what the left of the page footer shows.  Keep it under 32
# characters: groff has that much room for it at the default 80 columns and
# ellipsises the rest, which is what became of the longer description that
# used to be here.  Passing it at all costs the version its place in the
# footer, help2man having nowhere else to put it, which is the trade taken.
#
# help2man has to run the program it documents, which a cross build cannot do,
# so the generated pages are kept in the source and refreshed here only when
# building natively.  A native build that changes one is telling you the help
# text moved and the new page wants committing.
