Is Cava Packager open source?

[Octavian Rasnita]

Hi,

I read something about the free license of using Cava, but I didn't 
understand if it is open source also and I didn't find its source code.

I am interested in its source because I am trying to find if I can do 
something to make it accessible for Orca screen reader under Linux.
Seems that there is no other alternative of deploying WxPerl apps that 
really works and it is too bad that it can't be totally used in CLI mode or 
with an accessible GUI version.
