%description
The GNUstep Objective-C runtime is designed as a drop-in replacement for the 
GCC runtime. It supports both a legacy and a modern ABI, allowing code compiled 
with old versions of GCC to be supported without requiring recompilation. 
The modern ABI adds the following features:

* Non-fragile instance variables.
* Protocol uniquing.
* Object planes support.
* Declared property introspection.

Both ABIs support the following feature above and beyond the GCC runtime:

* The modern Objective-C runtime APIs, introduced with OS X 10.5.
* Blocks (closures).
* Low memory profile for platforms where memory usage is more important than speed.
* Synthesised property accessors.
* Efficient support for @synchronized()
* Type-dependent dispatch, eliminating stack corruption from mismatched selectors.
* Support for the associated reference APIs introduced with Mac OS X 10.6.
* Support for the automatic reference counting APIs introduced with Mac OS X 10.
