Origin

---

I started this project while developing an Android app with a friend. We were originally using HTTP which was far too heavy considering the small size and simplistic nature of our client server messages. CHUMP provided us with a protocol that is very lightweight in library size, data overhead, and speed while still being sufficient for our needs. CHUMP may be useful to you for another purpose.
