I will be presenting Hecl at OSCON this summer!

I’m pretty excited about it, and have been brushing up Hecl a bit, although I need to do a new release. For the moment, getting it from subversion is your best bet. I’m really looking forward to going home to Oregon, and getting to go to a cool conference and present at it, too!
I hope to see you there!
