Pascal,
Yes to a. For b the main-binary also renames the binary to the value of
cfBundleExectutable from the bundle's Info.plist appending '-bin' if there's a
launcher script set in the bundle file in which case the launcher script is
renamed to the cfBundleExecutable value. It strips all of the preceding path
information as well. LaunchServices (that's the daemon that actually executes
when you run `open` from the command line or double-click an app bundle in
Finder) reads Info.plist and runs the file indicated by cfBundleExecutable.
