unpacking a darwin port

[.dan.]

I downloaded the darwin port of lynx.  It has a ".tar.bz2" extension.  I
have used gzip and gunzip for ".gz" compressed files but I 'm not familiar
with the above "bz2" extension.

What do I use at the leperd terminal to uncompress it?  What then is the
tar command to get the individual files?

Thanks.
