Invoke script with Add-In

[msherman]

A couple of questions:

- Is there a way to invoke a script from an Add-In method? My intention is to observe the project for hierarchy changes and update a tagged value field using a script that I have setup already.

- Which is the correct event to respond to? It's not crystal clear to me which action fires the events OnContextItemChanged and OnNotifyContextItemModified. I'm mostly interested in a change in a package's alias property and a change in the hierarchy of sub-elements in the hierarchy.

Thanks for any and all
