[Cuis-dev] Question about package building and system classes

[Mauro Rizzi]

Hello Phil!

Thanks a lot, the postPackageInstall and postPackageInstall methods will
resolve multiple of my concerns!

I'm gonna use this chain and ask, the package manager doesn't actually
remove the packages when you click remove right? So in theory I shouldn't
worry about having that var removed when someone removes the package
correct?.

Cheers!
