| DEROFF(1) | DEROFF(1)
| NAME
| deroff, delatex – remove formatting requests
SYNOPSIS
| `deroff` [ option ... ] file ...
`delatex` file
DESCRIPTION
| Deroff reads each file in sequence and removes all nroff and troff(1) requests and non-text arguments, backslash constructions, and constructs of preprocessors such as eqn(1), pic(1), and tbl(1). Remaining text is written on the standard output. Deroff follows files included by `.so` and `.nx` commands; if a file has already been included, a `.so` for that file is ignored and a `.nx` terminates execution. If no input file is given, deroff reads from standard input.
The options are `−w` Output a word list, one ‘word’ (string of letters, digits, and properly embedded ampersands and apostrophes, beginning with a letter) per line. Other characters are skipped. Otherwise, the output follows the original, with the deletions mentioned above. `−_` Like `−w`, but consider underscores to be alphanumeric rather than punctuation. `−i` Ignore `.so` and `.nx` requests. `−ms −mm` Remove titles, attachments, etc., as well as ordinary troff constructs, from ms(7) or mm documents. `−ml` Same as `−mm`, but remove lists as well.
Delatex does for tex and latex (see tex(1)) files what `deroff −wi` does for troff files.

BUGS
| These filters are not complete interpreters of troff or tex. For example, macro definitions containing `\$` cause chaos in deroff when the popular `$$` delimiters for eqn are in effect.
Text inside macros is emitted at place of definition, not place of call.
