- * This file contains functionality for getting dart version numbers using
- * our standard version construction method. Systems that does not include this
- * file should emulate the structure for revision numbers that we have here.
- *
- * The version number of a dart build is constructed as follows:
- *   1. The major, minor, build and patch numbers are extracted from the VERSION
- *      file in the root directory. We call these MAJOR, MINOR, BUILD and PATCH.
- *   2. The svn revision number for the current checkout is extracted from the
- *      source control system that is used in the current checkout. We call this
- *      REVISION.
- *   3. If this is _not_ a official build, i.e., this is not build by our
- *      buildbot infrastructure, we extract the user-name of the logged in
- *      person from the operating system. We call this USERNAME.
- *   4. The version number is constructed as follows:
- *      MAJOR.MINOR.BUILD.PATCH_rREVISION_USERNAME
