@usage descriptions not parsed

[grasmash]

The README.md gives the following example implementation of the @Usage annotation:

     * @usage bet alpha --flip
     *   Concatenate "alpha" and "bet".

When executing a command with this annotation, the following is output:

my:cat bet alpha --flip

The description Concatenate "alpha" and "bet". does not appear.

This is a limitation of Symfony Console's help command. We definitely want the descriptions to show up in the help output.

[grasmash]

In the mean time, perhaps we should just update the documentation?

[greg-1-anderson]

Sure, that would be welcome.
