%description
This is a collection of four libraries which can be used to build
foreign function call interfaces in embedded interpreters.

It consists of two parts:
 * avcall - calling C functions with variable arguments.
   Its include file is <avcall.h>.
 * callback - closures with variable arguments as first-class C functions.
   Its include file is <callback.h>.

Additionally, you can determine the libffcall version by including
<ffcall-version.h>.

For backward compatibility with versions 1.x, libraries libavcall.{a,so}
and libcallback are installed as well. But they are deprecated;
use libffcall instead.
