Adobe has apparently open sourced some libraries- I (very brief) quick look shows me:

If you read my foreword <http://opensource.adobe.com/asl_foreword.html> you will see I give a great deal of credit to Boost and the libraries do depend on Boost. Although I'm not active on this list (too much traffic for me to track) - I do know many people here and have folks like Mat forward me information of interest. As for the question about the relationship of this work to Mat - ASL is the work of Adobe's Software Technology Lab - the team Mat is on, although Mat isn't working directly on these libraries at the moment - he and Alex Stepanov (another STLab member) are working hard on another project. Certainly they influence mine and Foster's work a great deal. I'd be happy to answer technical questions - either directly or though the ASL forum on SourceForge. Sean
