All .apps use more or less the same structure (a variant of a
'bundle', I think):
Contents
MacOS
Executables
...
Once the app is located, given that you know something about what
it's bundle contains, you can run the appropriate executable.
There are tracks that one can follow to get to the .app bundle, but
the ones I have found are 'circumstantial' and should be viewed with
suspicion :-}. I'd like to have a sure-fire way to locate the app,
rather than spend time pawing through old config files and trying
things out until one works.
The Finder has a database to let it associate a document with an app,
so that when you double-click a document, the proper app gets
launched. I don't know yet whether that's an available API, or just
something that Apple keeps locked in the Finder source.
