Tonight I bundled the cassandra command-line interface (CLI) into virgil. Since the CLI uses the thrift-based CassandraDaemon, the main method now starts a thrift server along side the REST server.
Now, when you (or your application) issues commands through the REST interface, you can verify that they worked through the command-line interface. For more information, check out the wiki.
Specifically, if you use the curl commands in the Getting Started section. You should see the following in the command-line interface.
