OK, you guys. You asked for it, you got it. :CUBE will
now accept typed-in cube configurations. The ^F command
(control f) to installed :cube prompts for a standard
ITS file name. If you give ? as the file name, it tells you
the thing I'm about to tell you.

The hack is as follows. You copy AI:BSG;CUBE TEMPLT into
some choice name of your own, and follow what it says
inside of it, editing it to look like your cube configuration.
Then enter :cube, and give the file name in response to ^F.

We do only the most rudimentary checking, for syntax,
center duplications, only six colors, overambitious file munging.
We have not yet put in conservation of cubies, let alone
ALAN's necessary and sufficient solubility conditions. So
it's quite possible to make :cube go blarmy in this way, so
be careful.

Occasionally, :CUBE may give an ambiguous description of a 180-degree
center-slice twist: to disambiguate it, let it do it, and see
what it did, and do it on your cube.
