.SH DESCRIPTION
These programs rearrange files for appearance's sake.
All read the standard input and write the standard output.
Some optionally read from files instead.
.PP
.I Col
overlays lines to expunge reverse line feeds
(ESC-7)
and half line feeds (ESC-9 and ESC-8)
as produced by
.I nroff
for .2C in
.IR ms (7)
and for 
.IR tbl (1).
It normally emits only full line feeds;
option 
.B \-f
(fine) allows half line feeds too.
Option 
.B \-b
removes backspaces, printing just one of each pile of overstruck
characters.
.I Col
normally converts white space to tabs;
option
.B \-x
overrides this feature.
Other escaped characters and non-printing characters, except for
SO and SI, are ignored.
.PP
.I Col
should not be used for printing on an HP ThinkJet printer with
.IR think (9.1),
which performs the
.I col
function itself.
.PP
Commands
.I "2, 3, 4, 5, 6"
convert their input to 2-, 3-, 4-, 5-, or 6-column form.
.PP
.I Mc
prints in as many columns as will fit on
.IR N -column 
`paper' (default
.IR n = 80).
If an input line ends in a colon `:', a `break' occurs; thus
`ls directory1 directory2 | mc' lists each directory
separately.
This feature is suppressed if option
.B \-
is present, or if input is from a file.
On output, multiple spaces are converted to tabs; this
is suppressed by option
.BR \-t .
.PP
.I Expand
replaces tabs by spaces.
The optional
.I stops
argument is a comma-separated of tab stop postions, counted from 0;
default is every 8 columns.
.PP
.I Fold
inserts newlines after each
.I N
characters (default
.IR n =80)
of long lines.

.SH BUGS

handle more than 800 characters per line,
and understands VT (013) as reverse line feed.
