lrzsz is a X/Y/ZModem package built from the public-domain version of
Chuck Forsberg<B4>s rzsz package. This package contains NO code from later
releases of rzsz which would preclude it from being released under the GPL.
It has been heavily modified by me and others.

Please note that credit should be given to Chuck Forsberg (rzsz) and Stephen
Satchell/Satchell Evaluations (crc routines) for this package. Any later
modifications were minor and merely introduced to increase performance,
reliability or compatability.
