[9fans] bdf2subf

["Skip Tavakkolian" <fst@centurytel.net>]

I finished my attempt at bdf2subf.  I've run it against several bdf
files I found on the net, and feel comfortable enough to put it out
for limited testing.  It has correctly handled well formed files, and
has caught syntax problems in a few files that were in error based on
my reading of the specifications.  If anybody is interested email me
for the sources.  If there is enough interest, I will mail to the list.

pseudo man page:

usage: bdf2subf [-r] -f bdfile [hex-hex]

-r	prints the contiguous ranges in the BDF file (for later input to
	itself).  The printed ranges represent the value of the ENCODING
	keyword in the BDF file.
hex-hex is the range of chars to extract in hex.  (values of the
	ENCODING keyword).

to convert a whole bdf file use something like:

	for (i in `{bdf2subf -r -f infile.bdf}) {
		bdf2subf -f infile.bdf $i > 'U+'^$i
	}
to generate a range of Subfont files.

Format of the BDF file needs to conform to the "Glyph Bitmap
Distribution Format (BDF) Specification", Version 2.2 (22 March 1993)
