> The pig script stored in: conf#'pig.script' has the whitespace removed, this makes it
difficult to extract and run the
> script. In particular, statements that terminate in ";" work correctly as
> "statement1;statement2;statement99"  but statements that do not end in ";" result in
> "statement1statement2statement3" and it's difficult to parse the pig script and fix the
concatenated string.
> There's also a problem with comments as in:
> /*mycomment*//*more comments*/ PIG_CODE //comment PIG_CODE
> On a side note, I also noticed that in many of the scripts the last statement is missing
";"
