From the Fritzing website:
"We are creating a software and website in the spirit of Processing and Arduino, developing a tool that allows users to document their prototypes, sharethem with others, teach electronics in a classroom, and to create a pcb layout for professional manufacturing."
I'll be trying my hands on the Fritzing software next time I work on an Arduino project. Maybe one day I'll even have time to go back and fix my older posts to have better documentation à la Fritzing! :)
