Name	Type	Description
TcpServerListener	simple module	Opens a TCP socket to listen on a port, accepts incoming connections, and dynamically creates modules to handle them. The type of modules to be created can be specified in a parameter. The new modules will be appended to the connection[] submodule array of the parent of this module, i.e., they will be siblings of this module.

//
// Accepted TCP connections will inherit the `autoRead` setting of this module. To
// allow rate limiting on the connections, set autoRead=false here, and use
// corresponding parameters of the connection handling module (e.g., `readSize` and
// `readDelay`) to set a rate limit. This will allow TCP flow control to come into
// effect.
