+.Sh NAME
+.Nm colcrt
+.Nd filter nroff output for CRT previewing
+.Sh SYNOPSIS
+.Nm colcrt
+.Op Fl
+.Op Fl \&2
+.Op Ar
+.Sh DESCRIPTION
+.Nm Colcrt
+provides virtual half-line and reverse line feed sequences
+for terminals without such capability, and on which overstriking
+is destructive.
+Half-line characters and underlining (changed to dashing `\-')
+are placed on new lines in between the normal output lines.
+.Pp
+Available options:
+.Bl -tag -width Ds
+.It Fl
+Suppress all underlining.
+This option is especially useful for previewing
+.Em allboxed
+tables from
+.Xr tbl 1 .
+.It Fl 2
+Causes all half-lines to be printed, effectively double spacing the output.
+Normally, a minimal space output format is used which will suppress empty
+lines.
+The program never suppresses two consecutive empty lines, however.
+The
+.Fl 2
+option is useful for sending output to the line printer when the output
+contains superscripts and subscripts which would otherwise be invisible.
+.El
+.Sh EXAMPLES
+A typical use of
+.Nm colcrt
+would be
+.Bd -literal
+tbl exum2.n \&| nroff \-ms \&| colcrt \- \&| more
+.Ed
+.Sh SEE ALSO
+.Xr nroff 1 ,
+.Xr troff 1 ,
+.Xr col 1 ,
+.Xr more 1 ,
+.Xr ul 1
+.Sh BUGS
+Should fold underlines onto blanks even with the
+.Ql Fl
+option so that
+a true underline character would show.
+.Pp
+Can't back up more than 102 lines.
+.Pp
+General overstriking is lost;
+as a special case
+.Ql \&|
+overstruck with
+.Ql \-
+or underline becomes
+.Ql \&+ .
+.Pp
+Lines are trimmed to 132 characters.
+.Pp
+Some provision should be made for processing superscripts and subscripts
+in documents which are already double-spaced.
+.Sh HISTORY
+The
+.Nm
+command appeared in 
+.Bx 3.0 .
