question about m4 - macro preprocessor

Tue Nov 20 07:35:02 AEST 1990

i am using the macro preprocessor m4 with files that are
subsequently passed to troff. m4 replaces lines that 
contain m4 commands with blank lines. the blank lines
disrupt the text that is passed to troff. does anyone know 
how to run m4 so that the blank lines can be eliminated?
