PWB/UNIX troff source code (1977)

This is the source code for the original AT&T version of troff, dated May 1977-1978. It was extracted from a tarball holding the original PWB source published by The Unix Heritage Society:

The files in this repository's root directory are garnish added for VCS or GitHub-specific purposes. Everything in the immediate subdirectories has been left untouched from their extraction. The file timestamps date are back to October 25th, 1978.
