Originally, this was going to be a meta-package for
swig-{build,python,perl,...}, but SWIG no longer has run-time
components, and may now be collapsed into a single package.
SWIG (Simplified Wrapper and Interface Generator)
SWIG is a compiler that integrates C and C++ with languages including
Perl, Python, Tcl, Guile, Mzscheme, Java, Ruby, PHP, and Ocaml.
SWIG reads annotated C/C++ header files and creates wrapper code (glue
code) in order to make the corresponding C/C++ libraries available to
the listed languages, or to extend C/C++ programs with a scripting
language.
