This package defines a high-level Galaxy workflow description termed "Format 2". At this point, these workflows are defined entirely client side and transcoded into traditional (or Format 1?) Galaxy workflows.
The traditional Galaxy workflow description is not meant to be concise and is neither readily human readable or human writable. Format 2 addresses all three of these limitations.
Format 2 workflow is a highly experimental format and will change rapidly in potentially backward incompatible ways until the code is merged into the Galaxy server and enabled by default.
