  tlaunchmode on
  tlaunchmode off

tlaunchmode switches a TeX Live installation between tlaunch mode
and classic mode.

tlaunchmode means:
- a launcher with menus and buttons instead of a submenu
- per-user configuration at first startup.
  This configuration can be undone from within the launcher
  and from the `Programs and Featurers' Control Panel item.

See the manual for additional details and customization options.
