In addition to Games::Sudoku::General, you will get the following
executable:

  sudokug -- an interactive interface to Games::Sudoku::General.

Unless you are running MSWin32 or VMS (which are special-cased),
I will assume you are running some version of U*ix, and behave
accordingly.

If you do not want this executable installed, rerun this script
with the -n qualifier.
