I’ve spent 15 years of my life working on Bundler. When I introduce myself, people say “oh, the Bundler guy?”, and I am forced to agree. I didn’t come up with the original idea for Bundler (that was Yehuda). I also didn’t work on the first six months worth of prototypes. That was all Carl and Yehuda together, back when “Carlhuda” was a super-prolific author of Ruby libraries, including most of the work to modularize Rails for version 3.
