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
Suppress all underlining. This option is especially useful
for previewing allboxed tables from tbl(1).
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 -2
option is useful for sending output to the line printer when
the output contains superscripts and subscripts which would
otherwise be invisible.
Display version information and exit.
Display help text and exit.
Should fold underlines onto blanks even with the '-' option so that a
true underline character would show.
Can't back up more than 102 lines.
General overstriking is lost; as a special case '|' overstruck with
'-' or underline becomes '+'.
Lines are trimmed to 132 characters.
Some provision should be made for processing superscripts and
subscripts in documents which are already double-spaced.
