 """
 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'.
