- All Rights Reserved.

- available on request. Vendors wishing to bundle this software as
- a non-source package in their software releases should contact me:

-
- 2) psdtwid and some of the character drawing and spacing
- stuff (bracket font in ps.lib) is from ditroff2ps/tpscript:
-
- Copyright: 1985, Stephen Frede, UNSW Australia
- Use it and copy it as much as you want, but don't pretend you
- wrote it, or sell it for profit.
-
- Michael Rourke wrote some of the code that I borrowed.
-
- Excellent stuff.
-
- 4) There are a few minor tweaks (specifically: headers on font width
- tables, and BSDHACK) influenced by David MacKenzie's (djm@wam.umd.edu or
- edf@rocky2.rockefeller.edu) and Sverre Froyen's (boulder!fesk!sverre,
- sunpeaks!seri!fesk!sverre) troff2lj package. No code was directly
- borrowed, and no copyright appears on the sources consulted.
- (troff2lj downloads SFP's, not incrementally, and doesn't support
- PK files)
-
- 5) The S.*.pk font files that I've distributed with this release are
- MATH8 encoded PK fonts, which are combination of several things:
-
- - characters from Donald Knuth's cmr, cmsy, cmmi TeX fonts.
- These are public domain.
-
- - Rick Richardson's cmtrf font (bracket building characters)
- from jetroff which Rick has graciously permitted me to
- distribute provided that they are only used with psroff.
-
- - Each S.*.pk file was created by converting them to SFP's,
- merging them into another SFP using the pk2sfp program
- (originally inspired by Ron Florence's makeS program),
- and converting them back to PK's using Rick
- Richardson's sfp2pk program (included in jetroff), and
- also available from the mims-iris font archives at waterloo.
-
- Sorry, I cannot distribute sfp2pk.
-
- See LASERFONTS on how to build psroff fonts from TeX PK's.
-
- 6) The manual page for CAT troff format was written by Henry Spencer
- at the University of Toronto. Without which this stuff would
- never have been written.
