sigh. my page timed out while I was editing this, and I ended up having to
cut and paste
the whole thing back together, and I (obviously) pasted the wrong paragraph
here. This
is the correct one:
This example is awesome! I tried out something similar in my test
environment, and it works great. My major issue with doing it this way
is that it means that I can't see from the class which packages it's
requiring, but it's still pretty nice that I only have to maintain one list
of packages. Also, it opens up a single point of failure for "all" classes,
if someone screws up this file. We may eventually go to something like
this and just wrap the editing of this file in a perl script with lots of
error
checking. lol
sorry for the confusion,
Michael
