I don't understand a thing with this program, its not something I'm busy with. Its a drawing program, but a special one. Its made for drawing Feynman diagrams. This is the English page

I did made a drawing from an example on the net. Found one problem. The "y" should be an ypsilon, it looks like an "y" but it is a little different.
Next program please!
