I have a WFT that calls an external task, which is basically a script written in Perl. In this script, I'm trying to load a DCR which contains data to determine which TPLs it should call iwpt_compile with.Should I be using iwpt_load_dcr() or iw_load_dcr()? What TeamSite Perl libraries do I need to include? I've been able to use iwpt_load_dcr() in a TPL before, but I didn't have to load any Perl modules because it's in a TPL.
