Hi Ron (and others),I think I've tightened things up according to your suggestions; I've split regular user install t tests vs xt/author tests, I reference metacpan and I also have a decent prereq list in Makefile plus smaller bits and pieces that caught my eye.
If nothing breaks I'll submit to PAUSE shortly; many thanks for your help!
ken1PS. It's possible I'll break the current git repo to start off clean, just a heads up...
