Scripting languages generally provide a C API which allows you to write
a wrapper, but trying to maintain such wrappers by hand for a large API
is quite a lot of work. SWIG helps to automate that job by generating
wrapper code which uses the available C API for you.
Often we can add a new method to the C++ API and need to do nothing
extra to have it available in the bindings. Sometimes it gets wrapped,
but we need to give SWIG some help to wrap it in the best way.
You might find this talk I gave at Kiwi PyCon 2011 helpful - there
are slides and recorded audio there:
