I'm not a lawyer, but my understanding of the license is that you cannot in general link to GPL code without making the whole binary fall under GPL. The LGPL allows a program to link to it without affecting the license of the program, though. You can however have your non-GPL code execute a separate GPL binary without affecting the legal state of your own code. The important part is that the programs are kept separate. /Johan Gill
