[erlang-questions] [ANN] yaml loader

You're right, that's a terrible name for this project.  I wanted the
main module to be "yaml" but that doesn't mean the application or
project has to be called that.  This project is now at:

https://github.com/goertzenator/goyaml

Apologies for those who already watched or forked.

Regarding streaming, libyaml forced me to go with an all-at-once
approach.  Erlang native processes would help overcome this, as would
a parser written in Erlang.
