    <https://mailman.jlab.org/pipermail/halld-offline/2017-August/002919.html>
    This version of sim-recon allows use of RCDB 0.02 which in turn
    allows use of Sascha Somov's new trigger simulation code.
 4. New HDGeant4: 1.4.0 and new version set version_2.15.1
    <https://mailman.jlab.org/pipermail/halld-offline/2017-August/002926.html>
    There are several changes to HDGeant4 in this version. The build was
    precipitated by the need fix the build to allow for inclusion of the
    new TAC library.
