I've seen a lot of tutorials showing one how to set up PHP/Python/Perl/RoR on nginx via various FCGI processes.

None of the tutorials that I found show one how to serve multiple FCGI services off one server.

How would one configure the stable nginx (nginx-0.7.64) to serve multiple FCGI processes (one for each of the above languages)?

Example addresses for each FCGI process are as follows:

127.0.0.1:8080 - PHP
127.0.0.1:8081 - Python
127.0.0.1:8082 - Perl
127.0.0.1:8083 - Ruby on Rails

An example configuration file that shows one how to implement multiple FCGI's off one server is really what I need. Perhaps others will benefit as well.
