        * PathResolver/selection.xml : added PathResolverSetOutputLevel
        * python/showReleaseNotes.py : simple script to get any release notes for the release
        * Tagging as PathResolver-00-02-28

2016-03-31 Will Buttinger <will@cern.ch>
        * When using from python (e.g. joboptions), PathResolver will auto-start the ApplicationMgr, to get the correct MessageSvc
        * Tagging as PathResolver-00-02-27

2016-03-08 Will Buttinger <will@cern.ch>
        * made default outputlevel of messaging service be info
        * Tagging as PathResolver-00-02-26
