43 * Setup: keep the structure of the original Adventure port, but use an
44 * internal copy of the data file, serving as a sort of virtual disk. It's
45 * lightly encrypted to prevent casual snooping of the executable.
47 * Also do appropriate things to tabs so that bogus editors will do the right
48 * thing with the data file.
