%description
    The dyncall library encapsulates architecture-, OS- and
    compiler-specific function call semantics in a virtual "bind
    argument parameters from left to right and then call" interface
    allowing programmers to call C functions in a completely dynamic
    manner. In other words, instead of calling a function directly,
    the dyncall library provides a mechanism to push the function
    parameters manually and to issue the call afterwards. This means,
    that a program can determine at runtime what function to call, and
    what parameters to pass to it. The library is written in C and
    assembly and provides a very simple C interface to program against.
    The library comes in very handy to power flexible message systems,
    dynamic function call dispatch mechanisms, closure implementations
    or even to bridge different programming languages. When it comes
    to language bindings, the dyncall library provides a clean and
    portable C interface to dynamically issue calls to foreign code
    using small call kernels written in assembly. Instead of providing
    code for every bridged function call, which unnecessarily results in
    code bloat, only a couple of instructions are used to invoke every
    possible call.
