Probably useful for getting some experience with these popular Unix editors.

jove      Lightweight EMACS implementation.  Should come with a tutorial
          program.
elvis     Simple vi implementation, similar to contest environment.
vim       Extended vi implementation.
pico      Trivial editor; everything you can possibly do is listed
          on the screen.  No advanced features.  Currently not in the
          contest environment, but will probably be added.
xedit     Does even less than pico.  Available only on Unix; not in this
          directory.

Executables are for DOS.
