2010 May 14                 CASA Developers' Meeting   1
    Jürgen’s talk on science priorities:
        EVLA and ALMA observation modes  daunting!
        ALMA depends entirely on CASA
        Growing CASA user community
        If CASA or ALMA fails, ramifications for the future!
    Nick’s talk on the roadmap:
        We’ve made progress on concerns, more to go
        Requiring design documents
        Formalizing closure process  incorporate comments
          It will still be represented by a flowchart (sorry)
        Discipline, discipline, discipline!
