Re: [Inkscape-devel] Extension loading example

I repeat: I'm really not schizo, responding to my own emails! ;) I cleaned up the example, and fixed the Makefile to work on both Linux and Win32. People can try it out if they want, to see a possible way(one of many good ones, I'm sure) that a plugin architecture for extensions might be implemented.
