As near as I can tell after a couple of weeks of experimentation,
wrapping *C* is a piece of cake with SWIG, and you get interfaces for
Ruby, Python, Perl, PHP, tcl, clisp, lua, pike and a couple of variants
of Scheme with little additional effort. Wrapping C++ with SWIG, on the
other hand, does require a bit more detailed reasoning. But the
documentation on the Ruby/C++ interface is very good, and if the C++ is
well-written, it's at least doable.
