2012-06-06 When writing troff macro code, which I did frequently lately, ``Nroff/Troff User's Manual'' is the best help. ``UNIX Text Pro- cessing'' is helpful, too. ``Text Processing and Typesetting with UNIX'' is less frequently consulted by me, but occasionally worth a look. Sometimes troff still confuses me. Today, this message [0] from Russ Cox helped me to get my verbatim source code macros working. Also, I came across mom. [1] There are still troff guys around. :-) [0] http://9fans.net/archive/2007/11/810 [1] http://www.schaffter.ca/mom/mom-05.html http://marmaro.de/lue/ markus schnalke
