[6,4]	[.LEX]		Lexical Analyser Generator

This is an implementation of the Unix program LEX, which generates
lexical analysers from regular expression grammars.

This is a restructured and modified version of Forsythe's LEX which
appeared in the original Decus C kit.

	1.	Restructured to optimize overlay structure on RSX
	2.	Edited to produce more strict syntax for new version
		 of compiler.
	3.	Debug code enclosed in #ifdef DEBUG/#endif, but enabled
		 as current overlay structure size won't change if it
		 is turned off (debug code isn't the "high nail").
	4.	M. Minow edited in documentation and BUILD stuff.

NOTE:	RSX overlay structure could use a bit more work.  In particular
	the file open and other FCS stuff could be structured and placed
	in the L1 co-tree, out of the root. (RBD)

	1.	Clean up "-v" printouts, specifically character class
		printouts.  It appears that the "range()" function
		has a bug, but I didn't dive into it.
	2.	Many minor mods to allow generation of analysers not
		requiring "standard I/O" library.  All lexlib routines
		except lexgetc(), lexerror(), mapch() and lexecho()
		now are independent of stdio.  "-s" generates the
		standalone flavor analysers.
	3.	Added "-e" switch ("easy" command line).  Saying
		  lex -e name
		is equivalent to
		  lex -i name.lxi -o name.c -t name
	4.	Added a few error messages.
	5.	Cleaned up generated code for readability.
	6.	Added LEX.HLP to kit.
