[sdk/kdesrc-build/docbook_historied_per_file] doc/cmdline: Add a --print-modules command line option.

Git commit a1a3089ddaa94f48a3910f2a94d3c89d34192054 by Michael Pyne.
Committed on 06/02/2014 at 05:20.
Pushed by ashark into branch 'docbook_historied_per_file'.

Add a --print-modules command line option.

Does about what it sounds like, but quicker. Useful for checking to see
what kdesrc-build is resolving module dependencies to. The beginning
output is intermixed but you can grep for "* Module list" if you want
and everything after will be module names.
