			About POLYHEDRON, version 2.1

POLYHEDRON is a computerized collection of 250 problems in solid geometry
based on an entirely new idea of learning (teaching) "deduction free
geometry".

The directory "POLYHEDR" contains 42 files, each of them being more or
less essential, so that erasing or damaging some of them could be fatal
for the whole application.

DO NOT EDIT text files, even though some phrases look ugly to you (due to
inadequate translation). "POLYHEDRON" won't work after that!

You can run "POLYHEDRON" on PCs either in WINDOWS or in DOS,
with EGA, VGA, and SVGA display. The program has been reported running
with difficulties in Windows NT.

POLYHEDRON is an essentially DOS application. When running in a window,
pictures "crawl". Running on the full screen is highly recommended. 

In "General Settings" you will certainly choose "Mouse" rather than
"Keyboard", if your mouse is connected to.

POLYHEDRON is slightly device dependent. So, if the mouse cursor
is in sight, the main menu won't respond to keyboard commands.

Choose "List" in "Problem Type" for the full list of problems under
the given classification.

Polyhedra data are randomized every time you start solving a problem,
so you cannot use old data in a new session.

Appeal "Help" whenever you have any problems with POLYHEDRON handling.

The author is sorry about eventual misuse of english terms and wishes
you to enjoy POLYHEDRON. He will be grateful for any sort of
information you would like to share with him, about POLYHEDRON using.
