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

                     51: .SH BUGS
                     52: Should fold underlines onto blanks even with the
                     53: `\fB\-\fR'
                     54: option so that
                     55: a true underline character would show; if we did this, however,
                     56: .I colcrt
                     57: wouldn't get rid of

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