        !            20: .SH DESCRIPTION
        !            21: .I Colcrt
        !            22: provides virtual half-line and reverse line feed sequences
        !            23: for terminals without such capability, and on which overstriking
        !            24: is destructive.
        !            25: Half-line characters and underlining (changed to dashing `\-')
        !            26: are placed on new lines in between the normal output lines.
        !            27: .PP
        !            28: The optional
        !            29: .B \- 
        !            30: suppresses all underlining.
        !            31: It is especially useful for previewing
        !            32: .I allboxed
        !            33: tables from
        !            34: .IR  tbl (1).
        !            35: .PP
        !            36: The option
        !            37: .B \-2
        !            38: causes all half-lines to be printed, effectively double spacing the output.
        !            39: Normally, a minimal space output format is used which will suppress empty
        !            40: lines.
        !            41: The program never suppresses two consecutive empty lines, however.
        !            42: The
        !            43: .B \-2
        !            44: option is useful for sending output to the line printer when the output
        !            45: contains superscripts and subscripts which would otherwise be invisible.

        !            55: .SH BUGS
        !            56: Should fold underlines onto blanks even with the
        !            57: `\fB\-\fR'
        !            58: option so that
        !            59: a true underline character would show; if we did this, however,

        !            66: Can't back up more than 102 lines.
        !            67: .PP
        !            68: General overstriking is lost;
        !            69: as a special case `|' overstruck with `\-' or underline becomes `+'.
        !            70: .PP
        !            71: Lines are trimmed to 132 characters.
        !            72: .PP
        !            73: Some provision should be made for processing superscripts and subscripts
        !            74: in documents which are already double-spaced.
