Due to my long time away from such matters, the proposed YAML engine for Java that I intended to create have not got so far. Right it seems as if YAML is a major bottleneck in JRuby, so I started looking around. Loo and behold, at http://jyaml.sourceforge.net/ there seems to exists something that's almost exactly what we need. So I've impromptu decided to discontinue my JAML project and instead tackle the task of making this engine work together with JRuby.
RubyGems is really close right now. Each step takes us closer and closer, and right now it feels as if we have 99.99% of everything needed. If just the SourceForge CVS-system could start working we could actually really get this of the ground now.
