#Script that can automatically compare each plugin's version between the current version and the last release version.
#And send the list of plugins that have potential version update issue in an email to the PMC members.
#For example, the org.eclipse.datatools.enablement.oda.xml plugin has version 1.2.1.v201104121500 in the last release 1.9.1.
#The plugin has apparently changes in 1.9.2 nightly build, with a later datetime stamp, but it still has version 1.2.1.
#So this plugin would be a candidate to alert the PMC that the plugin micro/minor/major version should have been incremented.
