Actually your post was one of the things that made me look at Lua :)

I don't really remember unfortunately, and I don't have a build
environment at the moment (new PC). I think it was around the 200 KiB
mark but that could be way off. Either way it was definitely too large
for targets with only 64 KiB for the plugin buffer.

I had a look at some of the tools to do this (e.g. swig and tolua++) but
the problem with using those is that the Rockbox plugin API isn't a
great match for scripting language use. A straight translation would
lead to a somewhat awkward API. So some degree of manual API building
will still be needed.
