In addition to this facility, rumen > includes readers for this information to return job and detailed task > information to other tools. > These other tools include a more advanced version of gridmix, and > also includes mumak: see blocked issues. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
