To make a new pic,
	make

The output should be something like
	yacc -d picy.y
	
	conflicts: 28 shift/reduce
	cc  -c y.tab.c
	rm y.tab.c
	mv y.tab.o picy.o
	lex  picl.l
	1174/1300 nodes(%e), 3365/3500 positions(%p), 514/600 (%n), 26763 transitions
	, 44/100 packed char classes(%k), 1313/1400 packed transitions(%a), 1035/1200 output slots(%o)
	cc  -c lex.yy.c
	rm lex.yy.c
	mv lex.yy.o picl.o
	cc  -c main.c
	...
	cc  -c pic2.c
	cc  -c pltroff.c
	cc -o pic pic*.o pltroff.o -ly -lm

You may have some trouble with Lex -- older versions of Lex have
default sizes of arrays set poorly, and the pic lexical phase
strains them.  If it complains about out of space in various ways,
such as "calloc returns 0" or more specific messages,
look at the output lines that say things like
"1174/1300 nodes(%e)" and decrease the corresponding %e line
at the top of picl.l to make the limit tighter.
I have done this fairly tightly already, but you might
squeeze a bit more if necessary.

If you are using the standard version of Troff (i.e., the one that
drives the Graphics Systems CAT), the following CAVEAT applies:

To set things up for your typesetter and troff, you may want
to diddle some defaults.  The typesetter type has to be set in main.c;
I have it set up for the Linotron 202, which is almost certainly
not what you want.  The -T option can be used for non-standard stuff.

The file UNDOC describes a couple of things that have been
added to PIC since TM-80-1272-2 (June 9, 1980).

Good luck.
