+mnihongo is a fairly clumsy troff post-processor that
+catches unicode characters that might be japanese,
+looks them up in a font file (currently
+/lib/font/bit/pelm/unicode.9x24.font) to get the
+bits, converts that to postscript, and dumps that
+in the output.
+
+Widths are taken from troff font Jp, which has at
+best a simple approximation to the truth.
+
+The program itself is normally called implicitly
+by loading the troff macro package -mnihongo, which
+does a .pi command.

+/*
+output language from troff:
+all numbers are character strings
+
+sn size in points
+fn font as number from 1-n
+cx ascii character x
+Cxyz funny char xyz. terminated by white space
+Nn absolute character number n on this font. ditto
+Hn go to absolute horizontal position n
+Vn go to absolute vertical position n (down is positive)
+hn go n units horizontally (relative)
+vn ditto vertically
+nnc move right nn, then print c (exactly 2 digits!)
+ (this wart is an optimization that shrinks output file size
+ about 35% and run-time about 15% while preserving ascii-ness)
+Dt ...\n draw operation 't':
+ Dl x y line from here by x,y
+ Dc d circle of diameter d with left side here
+ De x y ellipse of axes x,y with left side here
+ Da dx dy dx dy arc counter-clockwise, center at dx,dx, end at dx,dy
+ D~ x y x y ... wiggly line by x,y then x,y ...
+nb a end of line (information only -- no action needed)
+w paddable word space -- no action needed
+ b = space before line, a = after
+p new page begins -- set v to 0
+#...\n comment
+x ...\n device control functions:
+ x i init
+ x T s name of device is s
+ x r n h v resolution is n/inch
+ h = min horizontal motion, v = min vert
+ x p pause (can restart)
+ x s stop -- done for ever
+ x t generate trailer
+ x f n s font position n contains font s
+ x H n set character height to n
+ x S n set slant to N
+
+ Subcommands like "i" are often spelled out like "init".
