.TH GRAW_FORMAT 10.6
.SH NAME
graw \- graw file format
.SH DESCRIPTION
.I Graw_format
files are simple.
There is one primitive per line, each primitive indicated
by a single-character identifier.
All strings are enclosed in double quotes.
Definition
need not precede use, though in practice
.B graw
produces
.I ref
primitives first, and master definitions are seldom found outside libraries.
.PP
The argument to a
.I ref
(or include) command is searched for in the current directory and then in
.BR /lib/graw .
.PP
Syntax:
.PP
body:	prim | body prim 
.br
prim:	line | box | string | dots | macro | inst | ref | master
.br
line:	\fLl\fR point point
.br
box:	\fLb\fR rect
.br
string:	\fLs\fR chars disp point
.br
dots:	\fLd\fR rect
.br
macro:	\fLz\fR rect
.br
inst:	\fLi\fR chars point
.br
ref:	\fLr\fR filename
.br
master:	mstart body mend
.br
mstart:	\fLm\fR chars
.br
mend:	\fLe\fR
.br
rect:	point point
.br
point:	INT INT

.PP
.I Graw
string displacements are specified by five bit codes defined below:
.EX
/* string placement displacements */
#define	HALFX	1
#define	FULLX	2
#define	HALFY	4
#define	FULLY	8
#define	INVIS	16
.EE
.PP
Invisible
.I string\fRs
are typically defined for masters with connection points.
Though the text is usually not displayed or printed, the
remaining four bits should nonetheless specify a proper
displacement for the sake of back-annotation.
