-.TH DEROFF 1 "December 23, 1996"
-.SH NAME
-deroff \- remove troff and preprocessor constructs
-.SH SYNOPSIS
-.B deroff
-[-w]
-.RI { file(s) }
-.PP
-.SH DESCRIPTION
-.B deroff
-reads in the named files (or stdin if none are given) and strips out
-.B troff
-constructs and macros. The preprocessor
-.RB ( eqn ", " tbl ", " pic ", " grap ", and "vgrind )
-sections are removed entirely.
-The resulting output, suitable for spelling, is sent to stdout.
-.PP
-.SH OPTIONS
-.TP
-.I \-w
-output a word-by-word list, delimited by newlines.
-.PP
-.SH SEE ALSO
-.BR troff (1),
-.BR eqn (1),
-.BR pic (1),
-.BR grap (1) ,
-.BR vgrind (1) .
-.PP
-.SH BUGS
-.B deroff
-is not a full
-.BR troff (1)
-interpreter; in particular it doesn't know how to expand macros and how to
-treat
-.IR m[mse] "'s"
-registers.
-.br
-Macros are assumed to end with
-.I ..
-and are simply skipped.
-.br
-.B deroff
-can be fooled with circular
-.IR ".nx " requests.
-The
-.IR ".so " request
-deepness is limited.
-.PP
