[groff] Design and Implementation of *roff

[Mike Bianchi]

I asked Brian Kernighan if he had recollections and/or documents from the early
days of nroff.

        Hi, Mike --

        All of the roff programs originate from Jerry Saltzer's Runoff, done for
        CTSS.  [nt]roff was unusual in having programmable layout (the trap
        mechanism).  I don't recall any place where this was all written down
        in an orderly fashion, though it's interesting and maybe some enthusiast
        could take it on.  Maybe Doug McIlroy remembers -- he did a roff-like
        program, as did I, and several others.

        Brian
