  44 == NAME
  45
  46 colcrt - filter nroff output for CRT previewing
  47
  48 == SYNOPSIS
  49
  50 *colcrt* [options] [_file_ ...]
  51
  52 == DESCRIPTION
  53
  54 *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.
  55
  56 == OPTIONS
  57
  58 *-*, *--no-underlining*::
  59 Suppress all underlining. This option is especially useful for previewing _allboxed_ tables from *tbl*(1).
  60
  61 *-2*, *--half-lines*::
  62 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.

  65
  66 == HISTORY
  67
  68 The *colcrt* command appeared in 3.0BSD.
  69
  70 == BUGS
  71
  72 Should fold underlines onto blanks even with the *'-'* option so that a true underline character would show.
  73
  74 Can't back up more than 102 lines.
  75
  76 //TRANSLATORS: Keep {plus} untranslated.
  77 General overstriking is lost; as a special case '|' overstruck with '-' or underline becomes '{plus}'.
  78
  79 Lines are trimmed to 132 characters.
  80
  81 Some provision should be made for processing superscripts and subscripts in documents which are already double-spaced.
  82
  83 == EXAMPLES
  84
  85 A typical use of *colcrt* would be:
  86
  87 ____
  88 *tbl exum2.n | nroff -ms | colcrt - | more*
  89 ____
