    the code is already there. let's try :

    $ ln -s /tmp/tar /bin/pax
    $ ln -s /tmp/cpio /bin/pax
    $ /tmp/tar -?
    usage: pax [-]{crtux}[-befhjmopqsvwyzHLOPXZ014578] [blocksize] [archive]
               [replstr] [-C directory] [-I file] [file ...]

    $ /tmp/tar -?
    usage: pax -o [-aABcLvVzZ] [-C bytes] [-H format] [-O archive]
               [-F archive] < name-list [> archive]
    usage: pax -i [-bBcdfmnrsStuvVzZ6] [-C bytes] [-E file] [-H format]
               [-I archive] [-F archive] [pattern...] [< archive]
    usage: pax -p [-adlLmuvV] destination-directory < name-list
