+.Sh NAME
+.Nm deroff
+.Nd remove nroff/troff, eqn, pic and tbl constructs
+.Sh SYNOPSIS
+.Nm deroff
+.Op Fl ikpw
+.Oo
+.Fl m
+.Ar a | e | l | m | s
+.Oc
+.Op Ar
+.Sh DESCRIPTION
+.Nm deroff
+reads each file in sequence and removes all
+.Xr nroff 1
+and
+.Xr troff 1
+command lines, backslash constructions, macro definitions,
+.Xr eqn 1
+constructs (between
+.Dq .EQ
+and
+.Dq .EN
+lines or between delimiters),
+.Xr pic 1
+pictures,
+and table descriptions and writes the remainder to the standard output.
+.Nm
+follows chains of included files
+.Po
+.Dq .so
+and
+.Dq .nx
+commands
+.Pc ;
+if a file has already been included, a
+.Dq .so
+is ignored and a
+.Dq .nx
+terminates execution.
+If no input file is given,
+.Nm
+reads from the standard input.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl i
+Ignore
+.Dq .so
+and
+.Dq .nx
+commands.
+.It Fl k
+Keep blocks of text intact.
+This is the default behavior unless the
+.Fl m
+option is given.
+.It Fl m
+Enable support for common macro packages.
+The
+.Fl m
+option takes the following arguments:
+.Bl -tag -width Ds -offset indent -compact
+.It a
+recognize
+.Xr man 7
+macros.
+.It e
+recognize
+.Xr me 7
+macros.
+.It l
+remove list constructs.
+.It m
+recognize
+.Xr mm 7
+macros.
+.It s
+recognize
+.Xr ms 7
+macros.
+.El
+.It Fl p
+Preserve paragraph macros.
+This option only has an effect if the
+.Fl m
+option is also specified.
+.It Fl w
+Output a word list, one
+.Sq word
+(string of letters, digits, and apostrophes, beginning with a
+letter; apostrophes are removed) per line, and all other characters
+ignored.
+Normally, the output follows the original, with the deletions
+mentioned above.
+.El
+.Sh SEE ALSO
+.Xr eqn 1 ,
+.Xr nroff 1 ,
+.Xr pic 1 ,
+.Xr tbl 1 ,
+.Xr troff 1
+.Sh HISTORY
+.Nm
+appeared in
+.At v7 .
+.Sh BUGS
+.Nm
+is not a complete
+.Xr troff 1
+interpreter, so it can be confused by subtle constructs.
+Most errors result in too much rather than too little output.
+.Pp
+The
+.Fl ml
+option does not correctly handle nested lists.
