Pro Scripting language bindings (via swig) python, perl, tcl
Scripting language biddings are available via swig, supposedly any swig target could be used If you are okay with building, and probably maintaining, the project for your own needs then you may be able to build bindings for your favorite scripting platform.
As noted in a slant "con", there are no binary releases, including no prebuilt bindings.
Pro Cross platform

Cons
Con Only available to big studios
Con Small community

Con No binary releases.
Expect to compile this from source if your want to play with it.
Ubuntu has a package for it, but that package appears to be missing it's scripting language bindings. I expect the build is also quite old and i fear may be dropped in coming Ubuntu releases.
