Hi Chris,

Many thanks for your answer. 
I‘m still confusing about all this terminology in the Apache Qpid project.

For me the „Proton library“ is the library that lives under „proton“ namespace. 
As you very well remarked the answer was already in mine question but for the 
library 
that lives in the namespace“qpid::messaging“.

Beside this particular question it would be more interesting for me to know the 
relationship between these 2 libraries.Which one is better? There are 
recommendations to use one library for a new project?There are some use case 
scenarios that can be covered just by one library?

Best regards,
Daniel
