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
