[Ribbit-Developers] Generate ribbit messages from command line compatible with rattlegram

[W4CKX]

Hello Josh.

Thank you for reaching out.
The short answer is: Rattlegram and Ribbit are not compatible.

Rattlegram was put together very quickly by Ahmet reusing a lot of his
earlier CODFMTV work.
After Rattlegram demonstrated that it works, Ahmet went back to the design
board to build and optimize Ribbit from scratch.
Therefore Ribbit encoding improves on every measure compared to Rattlegram.

We are currently developing the Ribbit app to be a single codebase running
on all OS: Android, iOS, tablets, Windows, Linux and MacOS.

Let's keep in touch.
