usage:  CMSRF [-1] [-2] [-3] [-12] [-13] [-23] [-123] file1 [file2]


FORMAT

  CMSRF  reads  sorted  files, file1 and file2, and produces 1-, 2-, or 3-column
  output.  Column 1 contains lines found only in file1, column 2 contains  lines
  found  only  in  file2,  and  column 3 contains lines found in both files. The
  number option, [-n], specifies which columns you want to print.    To  compare
  unsorted files, use CMF (COMPARE_FILE).
