Command flags (OPTIONS) in man pages have to date been in haphazard order. Sometimes that order is sensible, e.g., most-important options first, but more often they're just in arbitrary places. This makes life hard for users. Here, I update the man-page-check Makefile script so it checks and enforces alphabetical order in OPTIONS sections. Then -- the hard part -- update all existing man pages to conform to this requirement. Signed-off-by: Ed Santiago <santiago@redhat.com>
