Splitting protocol buffer definitions into multiple .proto files

Question

I would like to include a protocol definition file in another protocol file. For example:

// base.proto: message P_EndPoint {   required int32 id = 1;   required string host = 2;   required int32 port = 3; } 

Then in another file:

communication.proto: // somehow include `base.proto' // ... message P_CommunicationProtocol {   required CP_MessageType type = 1;   optional int32 id = 2;   optional P_EndPoint identity = 3;   repeated P_EndPoint others = 4; } // ... 

(Note: developers.google.com is not available in my locale)
