This directory contains the TeX sources for "A Guide to TeX for the Troff User." It uses plain TeX augmented by some ad-hoc macros in "paperhead.tex". The file "intro.tex" contains \input control words that read the other .tex commands. So to produce the document, type tex intro and stand back. The final result will be intro.dvi and intro.log (plus TOC.tex, a table-of-contents file). Use your local TeX output driver to get the thing on hard copy or your Sun screen or whatever. TRW sites should change the top three lines of title.tex so as to produce the logo in the manner approved by the Corporate Identity office. If you are a TRW site and don't have the "trwlogo" font, you should obtain it from the Software Productivity Project.
