This recently came up on the mailing list
http://mail-archives.apache.org/mod_mbox/pig-user/201302.mbox/%3CCANSvDjrerbmRbTwkpb1B9Es%3DaaN-6kGyw8nwCSNenhnhNo%2BbjA%40mail.gmail.com%3E

Shell commands can be used in pig scripts, for eg to set HOME directory.

%default HOME `echo \$HOME`

This feature is very useful and should be documented.
