"Crossing the Red Sea" is shareware.  It is not free, nor
is it in the public domain.  Shareware is a distribution
method under which you, the user, get the opportunity to
try the software for a reasonable period of time in order
to decide if it meets your needs.  If you find that it does,
the purchase price, sometimes called a registration fee,
should be sent to the author.  Upon receipt of your payment,
you will receive the registered version of the program, 
which includes many additional features, a printed user's
manual, mail and phone support at no extra charge, and
notice of other similar products as they are released.  You
are encouraged to pass along copies of your shareware disk to
anyone who might be interested.  When you do this, please
make it clear that the program is not free but is shareware.
The registration fee for "Crossing the Red Sea" is $19.95.
Once you have decided to use the program, please send that
amount plus $1 (in USA) to cover postage and handling to:
