2.2 release of ``The Macro Implementation of SNOBOL4 in C'' (CSNOBOL4)

This is a free port of the original SIL (SNOBOL4 Implementation
Language) "macro" version of SNOBOL4 (developed at Bell Labs) with the
`C' language as a target.

SNOBOL4, while known primarily as a string language excels at any task
involving symbolic manipulations.  It provides dynamic typing, garbage
collection, user data types, on the fly compilation.

The latest release can always be found at http://www.regressive.org/snobol4/csnobol4

Also useful are the Catspaw Vanilla SNOBOL4 manual;

Acknowledgments;

	First and foremost, I would like to thank Ralph Griswold, for
	all his invaluable help and time digging up old documentation!
	(as well as his work of 50 years ago, designing and
	implementing the language)!

	I would also never have succeeded without the help of Mark
	Emmer of Catspaw and his excellent SPARC SPITBOL product
	(used to bootstrap this implementation).

	The contributions of source code by Mark Emmer (SNOBOL4+) and
	Viktors Berstis (Minnesota SNOBOL4) have allowed me to advance
	the state of CSNOBOL4 in ways that would have been difficult or
	impossible.

The following have also provided help, encouragement, support, input,
historical background, testing, fixes, testing, money, etc
