Kernighan's rewrite of Osanna's TROFF

from Groff history:
"Unfortunately, Ossanna's troff was written in PDP-11 assembly language and produced output specifically for the CAT phototypesetter. He rewrote it in C, although it was now 7000 lines of uncommented code and still dependent on the CAT. As the CAT became less common, and was no longer supported by the manufacturer, the need to make it support other devices became a priority. However, before this could be done, he was killed in an auto accident.

So, Brian Kernighan took on the task of rewriting troff. The newly rewritten version produced a device independent code which was very easy for postprocessors to read and translate to the appropriate printer codes. Also, this new version of troff (called ditroff for `device independent troff') had several extensions, which included drawing functions. "
