This parser is written against the YAML 1.2 specification. It may
therefore be used as a JSON parser as well.
The project is an Erlang application. The module "yaml_parser" parses a
YAML source (a string, a file, whatever) and runs a callback function
for each token scanned. It's more or less like a SAX XML parser.
The testsuite provided isn't complete yet, though it contains all the
example found in the specification.
