                     47: .Sh DESCRIPTION
                     48: .Nm Colcrt
                     49: provides virtual half-line and reverse line feed sequences
                     50: for terminals without such capability, and on which overstriking
                     51: is destructive.
                     52: Half-line characters and underlining (changed to dashing `\-')
                     53: are placed on new lines in between the normal output lines.
                     54: .Pp
                     55: Available options:
                     56: .Bl -tag -width Ds
                     57: .It Fl
                     58: Suppress all underlining.
                     59: This option is especially useful for previewing
                     60: .Em allboxed
                     61: tables from
                     62: .Xr tbl 1 .
                     63: .It Fl 2
                     64: Causes all half-lines to be printed, effectively double spacing the output.
                     65: Normally, a minimal space output format is used which will suppress empty
                     66: lines.
                     67: The program never suppresses two consecutive empty lines, however.
                     68: The
                     69: .Fl 2
                     70: option is useful for sending output to the line printer when the output
                     71: contains superscripts and subscripts which would otherwise be invisible.
                     72: .El
                     73: .Sh EXAMPLES
                     74: A typical use of
                     75: .Nm colcrt
                     76: would be
                     77: .Bd -literal

                     86: .Sh BUGS
                     87: Should fold underlines onto blanks even with the
                     88: .Ql Fl
                     89: option so that
                     90: a true underline character would show.
                     91: .Pp
                     92: Can't back up more than 102 lines.
                     93: .Pp
                     94: General overstriking is lost;
                     95: as a special case
                     96: .Ql \&|
                     97: overstruck with
                     98: .Ql \-
                     99: or underline becomes
                    100: .Ql \&+ .
                    101: .Pp
                    102: Lines are trimmed to 132 characters.
                    103: .Pp
                    104: Some provision should be made for processing superscripts and subscripts
                    105: in documents which are already double-spaced.
                    106: .Sh HISTORY
