Debian README for twm package For information on the /etc/X11/twm/system.twmrc file, see the twm(1) manual page. Note that /etc/X11/twm/system.twmrc is auto-generated from the /etc/X11/twm/system.twmrc-menu file, so as to be able to support the Debian menu system. You should therefore make your customizations to /etc/X11/twm/system.twmrc-menu. After the update-menu command is run, they will appear in /etc/X11/twm/system.twmrc and be used by the twm binary. Some examples of .twmrc files from days of yore are available in /usr/share/doc/twm/examples. Branden Robinson, 16 Aug 2000
