deroff -- (BSD) remove nroff, troff, tbl and eqn constructs

Synopsis

   /usr/ucb/deroff [-k] [-p] [-w] [-m(aelms)] file . . .

Description

The deroff command reads each file in sequence and removes all nroff and troff command lines, backslash constructions, macro definitions, eqn constructs (between .EQ and .EN lines or between delimiters), and table descriptions and writes the remainder on the standard output. deroff follows chains of included files (.so and .nx commands); if a file has already been included, a .so is ignored and a .nx terminates execution. If no input file is given, deroff reads from the standard input file.

Options

-k: When used with -ma, -me, -ml, -mm, -ms options, the -k option will include text blocks that would normally be removed, such as those between macros .nf and .fi.
-p: Will keep the paragraph notations included in the text (.P macro).
-w: Generate a word list, one word per line. A ``word'' is a string of letters, digits, and apostrophes, beginning with a letter; apostrophes are removed. All other characters are ignored.

The -m option may be followed by an a, e, l, m, or s.

-ma: Interpret macros as man macros
-me: Interpret macros as me macros
-ml: Interpret macros as mm macros and delete lists
-mm: Interpret macros as mm macros
-ms: Interpret macros as ms macros

Notices

deroff is not a complete troff interpreter, so it can be confused by subtle constructs. Most errors result in too much rather than too little output.

deroff does not work well with files that use .so to source in the standard macro package files.
