ObjectiveAmiga is a runtime system and class collection for the Objective C. It is based on the GNU Objective C runtime system which comes with GNU CC 2.5.8. ObjectiveAmiga is subject to the same licensing conditions as the GNU CC 2.5.8 Objective C runtime.

ObjectiveAmiga consists of 5 parts:

• The runtime system (almost completely functional):
  A standard Objective C runtime system based on libobjc.a as supplied with gcc 2.5.8 but with some AmigaOS specific modifications. My runtime system also tries to be compatible as far as possible (I can't test it...) with the original gcc, with the NeXTSTEP and in some points with the Stepstone runtime system. Note that not the whole runtime system is indeed contained in `libbjc.a'. More and more parts are being moved over into the shared runtime library `objc.library' which is required by all ObjectiveAmiga applications.
• The shared runtime library (under development; functional):
  Traditionally Objective C programs carry a huge overhead in their code, due to the big runtime system. ObjectiveAmiga tries to minimize this problem by moving as many as possible parts from the linker library into a shared library which is placed into `libs:' instead of being linked to all executables directly.
• The basics library (very rudimentary):
  A class library loosely based on the basic classes of Stepstone's ICpak101. This library might depend in some places on my runtime system, but it doesn't make direct use of AmigaOS. Thus it should be portable, at least to some degree.
• The AmigaOS support library (under development; functional):
  This library tries to encapsulate some AmigaOS functions in Objective C classes. This is some kind of `AppKit' for ObjectiveAmiga. I am including several classes (e.g. `RexxHost' and `FileList') which are based on more or less reusable C code which I have already used in multiple C programs.
• The GUI library (under development; functional)
  This library (`libobjtriton.a') encapsulates the `Triton GUI creation system' into Objetive C classes in order to make it usable more easily in connection with `libobjam.a'.
