Allen Wittenauer updated PIG-1293:
----------------------------------
Attachment: PIG-1293.txt
Since we require bash, we can cheat a bit. BASH_SOURCE should contain the full
path to the script that we are executing. This means we can ... piggyback...
off of that variable to figure out where our real PIG_HOME is at.
> pig wrapper script tends to fail if pig is in the path and PIG_HOME isn't set

> If PIG_HOME isn't set and pig is in the path, the pig wrapper script can't
> find its home. Setting PIG_HOME makes it hard to support multiple versions
> of pig.
