10: output language from troff:
11: all numbers are character strings
12:
13: sn size in points
14: fn font as number from 1-n
15: cx ascii character x
16: Cxyz funny char xyz. terminated by white space
17: Hn go to absolute horizontal position n
18: Vn go to absolute vertical position n (down is positive)
19: hn go n units horizontally (relative)
20: vn ditto vertically
21: nnc move right nn, then print c (exactly 2 digits!)
22: (this wart is an optimization that shrinks output file size
23: about 35% and run-time about 15% while preserving ascii-ness)
24: Dt ...\n draw operation 't':
25: Dl x y line from here by x,y
26: Dc d circle of diameter d with left side here
27: De x y ellipse of axes x,y with left side here
28: Da x y r arc counter-clockwise by x,y of radius r
29: D~ x y x y ... wiggly line by x,y then x,y ...
30: w paddable words space -- no action needed
31: nb a end of line (information only -- no action needed)
32: b = space before line, a = after
33: p new page begins -- set v to 0
34: #...\n comment
35: x ...\n device control functions:
36: x i init
37: x T s name of device is s
38: x r n h v resolution is n/inch
39: h = min horizontal motion, v = min vert
40: x p pause (can restart)

42: x t generate trailer
43: x f n s font position n contains font s
44: x H n set character height to n
