 Therefore, if you write any Python 3 scripts that require a new third-party
 Python library, we must add it here to ensure that it is available in
 production.
 
-This used to be part of the Server build itself, but as it grew somewhat more

-cbdeps 1.0 package (ie, here in tlm/deps/packages rather than driven by a

-build. This also means we can keep the couchbase-server-specific Black Duck
-manifest here in the same location as construct.yaml, making it easier to keep
-them in sync.
