How to automatically increase the number of Android projects in Eclipse (prefer a portable solution)

ant [-Dmanifest.file=<file>] [-Dversion.file=<file>] [-Dbuild.slot=<number>]
    -Dmanifest.file - path and filename AndroidManifest.xml. Default: AndroidManifest.xml in a folder with build.xml
    -Dversion.file - path and file name in which to store the number Build version. Default: version.properties folder with build.xml
    -Dbuild.slot - position of build number in version array. Default: 2, ie X.X.build.
