deroff - Deletes neqn, nroff, and tbl constructs
deroff [-i|-l] [-kpuw] [-ma|-me|-mm|-ms] file...
deroff [-i|-l] [-kpuw] -mm -ml file...
command reads the specified files (or
standard input by default), removes all
macro calls, backslash constructs,
lines and between delimiters), and
descriptions, replacing many of them with spaces or blank lines,
and writes the remainder of the file to standard output.
Suppresses processing of included files (.so and .nx). Keeps blocks of text specified by requests or macros; for example, the .ne request. Suppresses processing of included files whose names begin with /usr/lib (such as macro files in /usr/lib/tmac). Interprets man macros only. Interprets me macros only. Ignores mm macros and deletes mm list structures. The -mm option must be specified with this option. Interprets ms and mm macros only. Interprets ms macros only. Performs special paragraph processing. Removes _\b and \b in underlined and boldfaced words. Automatically sets the -w option. Formats output into a word list, containing one word per line, with all other characters deleted.
In text, a word is any string that contains at least two letters and is composed of letters, digits, ampersands (&), and apostrophes ('). In a macro call, a word is a string that begins with at least two letters and contains a total of at least three letters. Delimiters are any characters other than letters, digits, ampersands, and apostrophes.
Trailing ampersands and apostrophes are removed from words.
command normally follows chains of included
processes those files. If a file was already included, a
naming it is ignored and a
naming it ends execution.
command is not a complete
interpreter, so it may not handle complex constructs well. Most
errors result in too much rather than too little output.
