Akka - verify installation

Question

I have installed Akka and need to verify whether the installation is successful. I simply used

akka -version

but this gave an error. What would be the reason? Does akka not supporting -version? This is the error it is reporting

Starting Akka...

Akka doesn't support the -version command. One way to find out if your installation works is running a simple boot class, as Akka suggests:

>  akka
No boot classes specified
Usage: bin/akka org.somewhere.BootClass
