awa5x 2.0.0 has been released:
https://github.com/Stark-Night/awa5x/releases/tag/v2.0.0It's a new major version because it introduces a debugger. This tool is not meant to be used directly, but it's supposed to be invoked through e.g. the exec system call as part of a more detailed user interface. Read the documentation for more details.
As of now there is no "fallback" porcelain included so if you want to use the service you either go in raw and send actual bytes or you write your own.
