/*
** ObjectiveAmiga: Interface to class Application
** See GNU:lib/libobjam/ReadMe for details
*/


// This class serves the same purpose as the similiarly named NeXTSTEP class.
// It does this in a completely different way though, because this is the only
// way that makes sense under AmigaOS. The clients of an ObjectiveAmiga
// Application will have more work to do themselves. Application simply
// notifies them when the Exec Signals they requested are set.
//
// All clients have to conform to the <ExecSignalProcessing> protocol. They
// will be asked for the signal bits they accept with -execSignals. Whenever
// one or more of these bits is set, they will receive an -execSignals:
// message with the currently set bits as an argument.
//
// Each ObjectiveAmiga application may have only *one* Application object.
// This object is called OAApp and it is defined in libobjam.a.
