NAME
deroff - remove nroff, troff, tbl and eqn constructs
SYNOPSIS
deroff [ -w ] file ...
DESCRIPTION
Deroff reads each file in sequence and removes all nroff and troff com‐
mand lines, backslash constructions, macro definitions, eqn constructs
(between `.EQ' and `.EN' lines or between delimiters), and table de‐
scriptions 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.
If the -w flag is given, the output is a word list, one `word' (string
of letters, digits, and apostrophes, beginning with a letter; apostro‐
phes are removed) per line, and all other characters ignored. Other‐
wise, the output follows the original, with the deletions mentioned
above.

BUGS
Deroff is not a complete troff interpreter, so it can be confused by
subtle constructs. Most errors result in too much rather than too lit‐
tle output.
