 4.1.6 Preprocessors in 'man' pages
 ----------------------------------
 
 If a preprocessor like 'gtbl' or 'geqn' is needed, it has become common
 usage to make the first line of the man page look like this:
 
      '\" WORD
 
 Note the single space character after the double quote.  WORD consists
 of letters for the needed preprocessors: 'e' for 'geqn', 'r' for
 'grefer', 't' for 'gtbl'.  Modern implementations of the 'man' program
 read this first line and automatically call the right preprocessor(s).
