Linux on the desktop for the general Courant user population is relatively new, and it varies significantly from its predecessor, Solaris. Most notably, the desktop environment has changed, and for some users making the transition from Solaris to Linux, it will be necessary to eliminate set-up files that were used for running obsolete window managers, such as twm, fvwm, and OpenWindows. This can be done by running a program called "dotout," which will save the old environment files under "olddots" in your home directory. It is safe for anybody to run this program, except for some long-time Courant users, who still use the window managers mentioned above on Suns.
