R-Crypt
--------

R-Crypt is handy utility that allows you to encrypt .COM files but still leave
them executable. To invoke R-Crypt, just type "RCRYPT" followed by one or more
files that you wish to protect; wildcard are allowed, and the ".COM" extension
is assumed if none is given. The key is chosen by R-Crypt automatically, so
you don't need to supply one. This program works by encrypting your .COM
program and adding some decryption code to the end. The file decrypts itself
in RAM at runtime, leaving the actual file unaltered with each execution of
the encrypted program.
