 * Useage: filewriters pathname
 * Writes on stdout the list of people who can write the file.
 * This writer's list contains three tokens, the owner, the group, and
 * the 'all others' group, respectively.
 * If either group does not have write access, then that token is
 * replace with the token "NONE".  If the 'all others' group has
 * write access then that token is "OTHER".
 *
 * Notice that the owner of a file can always write it because the
 * owner can change the file access mode.
 *
 * BUG: should handle links correctly.
