tar and compress/uncompress

[psyxsgp at otago.ac.nz]

Does anyone know of a public domain version of tar
and of compress/uncompress ...
I have some archived source code that i would like to
dearchive and get going under msdos
(for reasons of utility rather than preference).

I need source for tar and compress/uncompress to
do this.

Thanks
