Script for auto-increasing the version on bleeding_edge.
The script can be run regularly by a cron job. It will increase the build
level of the version on bleeding_edge if:
- the lkgr version is smaller than the version of the latest revision,
- the lkgr version is not a version change itself,
- the tree is not closed for maintenance.
The new version will be the maximum of the bleeding_edge and trunk versions +1.
E.g. latest bleeding_edge version: 3.22.11.0 and latest trunk 3.23.0.0 gives
the new version 3.23.1.0.
This script requires a depot tools git checkout. I.e. 'fetch v8'.
