libcallback1 - 2.4-2 main

ffcall is a collection of libraries which can be used to build
foreign function call interfaces in embedded interpreters.
.
This package installs a shared library version of the callback library, which
provides closures with variable arguments as first-class C functions.
.
The use of this shared library is deprecated. The main libffcall library,
which embeds callback, should be preferred.
