  <!-- ===================== Property Definitions =========================== -->
  
  <!--

  Each of the following properties are used in the build script.
  Values for these properties are set by the first place they are
  defined, from the following list:

  * Definitions on the "ant" command line (ant -Dfoo=bar compile).

  * Definitions from a "build.properties" file in the top level
  source directory of this application.

  * Definitions from a "build.properties" file in the user's
  home directory.

  * Default definitions in this build.xml file.

  You will note below that property values can be composed based on the
  contents of previously defined properties.  This is a powerful technique
  that helps you minimize the number of changes required when your development
  environment is modified.  Note that property composition is allowed within
  "build.properties" files as well as in the "build.xml" script.

  -->

  <!-- Developer property. Set value=true if you want test https certificates issued
       (as there's a limit on how many real certificates you can be issued per week).
       If not testing can either uncomment this property or set value=false.
       BEWARE: iff test.mode is true (so https.testing gets set to minus-minus-staging)
       AND the default protocol is https (server.protocols contains https first), the 
       check-tomcat-running target and any other targets running an ant http condition
       to test the default GS DL URL (which will be over https) won't work.
       This is because the testing certificate is not trusted by clients, in this case
       the ant http condition. (Clients that are browsers can be set to temporarily
       trust the testing certificate, but don't know how to make ant do that, maybe it
       needs to be done at Java level.)
       Ant socket conditions to the URL will work because socket tests don't use
       the protocol, just the host and port.

      * if you already have a certificate, then you probably do not want to be running this target but the 'ant renew-existing-https-cert' target instead, to renew your existing certificate.
