%description
The GNUstep Objective-C runtime is a drop-in replacement for the GCC runtime.
It supports a legacy and a modern ABI. The modern ABI adds non-fragile
instance variables, protocol uniquing, blocks, declared property
introspection, synthesised property accessors, @synchronized and the
associated reference APIs.
