To use

/usr/local/bin/nlfind [-h] [-v level] [-V] [-n] [-N] [-l] dir [find_args ...]

    -h          print help message and exit
    -v level    set verbosity level (def level: 0)
    -V          print version string and exit

    -n          go thru the actions, but do not update any files (def: do the action)
    -N          do not process anything, just parse arguments (def: process something)

    -l          print newlines in files as $'\n'

                NOTE: If find_args are supplied, then -l requires use of -print0.
                      By default, if no find_args are used, -print0 is used by find.
                      Filenames are printed, via -print0 pipe, via: ls -d -B -1

    dir               start searching under dir
    [find_args ...]   additional find args (def: -print w/o -l, -print0 w/ -l)

Exit codes:
     0         all OK
     1         some internal tool exited non-zero
     2         -h and help string printed or -V and version string printed
     3         command line error
 >= 10         internal error
