Specifying tmp for tar

[Dotan Cohen]

I have a 2 GB bz2 archive that unzips to over 10 GB (wikipedia dump).
Although I have over 50 GB free in /home, / has only about 8 GB free.
Thus, as tar uses /tmp, the / filesystem fills up and I cannot
continue. How can I specify a tmp directory for tar in my home
directory? Note that man tar makes no mention of a tmp option.

Thanks in advance.
