The first version of wolflow (v0.0.1) has been released.
Wolflow is a workflow engine which implements [workflow patterns](
http://www.workflowpatterns.com/) in ruby.
`wolflow` is designed to provide workflow engine primitives as plain ruby
objects, with a simple yet extensive API which allows defining, extending,
and executing workflows. It leaves the rest of the details (business
language, storage, execution engine) to be implemented as a separate layer.
