in my rcp app I need to verify some things before the app starts (e.g.
that some system variable is set, that certain files exist etc). Is there
a preferred place to do this in an rcp app - which also uses a login
splash? At the moment I check all this in the main plugin's Activator.init
method.
When I detect an error I want to show a popup message - actually the same
as you get when Eclipse can't start: "An error has occurred. See the log
file..." Can I do that?
