         Here are some properties you may want to change/update:

         source.dir
             The name of the source directory. Default is 'src'.
         out.dir
             The name of the output directory. Default is 'bin'.

         Properties related to the SDK location or the project target should
         be updated using the 'android' tool with the 'update' action.

         This file is an integral part of the build system for your
         application and should be checked into Version Control Systems.

    <!-- Execute the Android Setup task that will setup some properties

         The rules file is imported from
            <SDK>/platforms/<target_platform>/ant/ant_rules_r#.xml

         To customize existing targets, there are two options:
         - Customize only one target:
             - copy/paste the target into this file, *before* the
               <setup> task.
             - customize it to your needs.
         - Customize the whole script.
             - copy/paste the content of the rules files (minus the top node)
               into this file, *after* the <setup> task
             - disable the import of the rules by changing the setup task
               below to <setup import="false" />.
             - customize to your needs.
