>From Moose Panel > ST DownArrow (I assume I can call this the STImporter) brings up the dialog attached.
Can you direct me to documentation describing what each of the dialog items does?
Specifically, and referring to the attached image...

1. What is the effect of merging classes and metaclasses ?

2. What is the difference between the two importers ClassPackageImporter and ClassCategoryImporter ?

3. What is the effect of each option for Importing Context ?

4. What is the difference between the five strategies to compute invocation candidates?

5. What is an "invocation candidates?" 

I've been browsing around trying to find anything and got nothing.
