10 __DESCRIPTION__
11
12
13 Colcrt provides virtual half-line and reverse line feed
14 sequences for terminals without such capability, and on
15 which overstriking is destructive. Half-line characters and
16 underlining (changed to dashing `-') are placed on new lines
17 in between the normal output lines.

20 The following options are available:
21 - Suppress all underlining. This option is especiallyuseful for previewing ''allboxed'' tables from tbl
22 (1).
23
24
25 -2
26 Cause all half-lines to be printed, effectively dou- ble 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 oth- erwise be invisible.

44 Should fold underlines onto blanks even with the - option so
45 that a true underline character would show.

48 Can't back up more than 102 lines.

51 General overstriking is lost; as a special case |
52 overstruck with - or underline becomes
53 +.

56 Lines are trimmed to 132 characters.

59 Some provision should be made for processing superscripts
60 and subscripts in documents which are already
