Version 2.0.0.Final of the Scribble Java tools has now been released, and implements version 1 of the Scribble Protocol Notation.
Subsequent versions of the language will look at further language extensions, to support (for example) parameterisation, fork/join, assertions, etc.
We would encourage anyone interested in this type of functionality to try out the language and tools, and provide feedback either through this forum, or by raising feature requests (or bugs) using the jira issue tracking system.
