  .Sh DESCRIPTION
! .Nm col
! filters out reverse (and half reverse) line feeds so that the output is
! in the correct order with only forward and half forward line
! feeds, and replaces white-space characters with tabs where possible.
  This can be useful in processing the output of
  .Xr nroff 1
  and
  .Xr tbl  1 .
  .Pp
! .Nm col
  reads from the standard input and writes to the standard output.
  .Pp
  The options are as follows:
! .Bl -tag -width "-l num  "
  .It Fl b
  Do not output any backspaces, printing only the last character
  written to each column position.
  .It Fl f
! Forward half line feeds are permitted (``fine'' mode).
! Normally characters printed on a half line boundary are printed
  on the following line.
  .It Fl x
  Output multiple spaces instead of tabs.
