New Revision: 5513
Added:
trunk/dev/core/test/com/google/gwt/dev/AboutTest.java (contents, props
changed)
Modified:

trunk/user/src/com/google/gwt/user/tools/WebAppCreator.java
Log:
- Deprecates the constants in About.java that contain version information
in favor of getters in the same class.
- Migrates all internal references to these contants the new getters.
- Migrates version string parsing logic in CheckForUpdates to About. A
new method to return the version as a 3 element array is available.
