Thank a bunch for the reply!

I have never used p.resolveFile() and am having a hard time finding  
documentation on it.  Is it Ant api or python?

  Would you use it directly inside <script>?  Would you use it for  
the sys.path.append() calls?  If so, how?

>> sys.path.append(".")
>>
>> # import re
>> import os
>> from buildUtil import *
>>
>> 3rdPartyFunction()
>> ]]></script>
>> </target>


Thanks again!
Sorry for my ignorance.
