With so many high-profile companies and others out there with Titan/Janus in production, I can only imagine that most, if not all, have written some higher-level tools for managing the database and, in particular, the schema.
This is a call to publish your tools. I'll go first. I whipped up a little 'describe' command to help make it easier to see the schema and statuses.
This shows the output after loading GraphOfTheGods and running through some of the examples in the docs.
./bin/gremlin.sh -i describe.groovy
