[erlang-questions] concurrent libraries for business applications

[Gergely Buday]

Hi,

I am doing research in concurrent programming and would like to read 
concurrent Erlang libraries for business applications.

What libraries should I read?

Clearly, there are important libraries for business applications that 
implement various standards that are not inherently concurrent. I would 
be interested in libraries that use concurrency heavily.
