Usage: setupcon [OPTION] [VARIANT]
Sets up the font and the keyboard on Linux console.
-k, --keyboard-only  setup the keyboard only, do not setup the font
-f, --font-only      setup the font only, do not setup the keyboard
--force          do not check whether we are on the console
-v, --verbose        explain what is being doing, try it if s.t. goes wrong
--save           copy the font and the console map in /etc/console-setup,
update /etc/console-setup/cached.kmap.gz
--save-only      only save; don't setup keyboard/font immediately
(implies --force)
-h, --help           display this help and exit
If VARIANT is not specified setupcon looks for the configuration files
(in this order) ~/.console-setup and if this doesn't exist then the
combination/etc/default/keyboard + /etc/default/console-setup.  When
a VARIANT is specified then setupcon looks for the configuration files
~/.console-setup.VARIANT and /etc/default/console-setup.VARIANT.
