Yes, that's what I want to do, I just didn't figure out the best way to
do it, thanks for the tips :-)

I, for one cannot use buildj master for now : waf doesn't seem to work
with python 2.5 and my pyyaml version wasn't compiled for 2.6 :-(

There is one such parser in the yaml branch of the repository (using the
tokenize module), but I don't like it much (it has some subtle
incompatibilities). I've also tried to port the parser from YAML::Tiny
perl module (uses regexps ex(ten|clu)sively ;-p). The result can be
found here :

I'm still not sure what's the best way for this. We definitely need
discussing this more.

See : for the file format and for a (slightly outdated) description
of the schema used.
