CPrAN as a protocol defines a method for the distribution, managing, and testing of Praat plugins, but this is independent of the specific implementation of that protocol.

The implementation is left to clients: programs that make use of that interface to communicate with a CPrAN-compatible server and make the necessary queries to get lists of plugins, check their dependencies, download the appropriate versions, etc.

There is currently only one experimental client written in Perl. While the client is still under development and more testing is welcome, the entire interface is implemented and the client is considered stable enough for using. Until a full spec is written, the implementation of the interface in the Perl client can serve to disambiguate details of the protocol.
