usage_description="
Creates TeamCity versioning for a given project

Requires a VCS root to already be configured and available - the ID provided as the second arg (defaults to 'TeamCity')

Recommend you create this VCS in the Root project and only enable on sub-projects since VCS sync with credentials omitted breaks its own VCS if you store it within the same project


Idempotent - detects if versioning is already configured for the given project and skips creation if so


If you want to force feature replacement of an already existing versionSetting configuration, set TEAMCITY_FORCE_FEATURE_REPLACE=1
