Audacity as a service

Hello everybody,

I’ve just installed Audacity, and I’d like to use its functionalities within a program I have to create.
I’ve seen that there is a library, Mezzo, but I haven’t find any documentation which explains how to use it.

Anyone could help me please?
If I want to use this library within a program, how can I do it? The program must be in a particular language?

Thanks!
