The installed manual page has an incorrect location for the system.twmrc file under FILES. It has "/usr/local/lib/X11/twm/system.twmrc" instead of the correct location "/usr/local/share/X11/twm/system.twmrc".
(In reply to sjrbulk from comment #0) This is a problem that has been corrected upstream already about 7 months ago, but there hasn't been a release since. We could pull this in as a simple patch.
