Adding mongrel's prefix functionality to spawner
Why add mongrels prefix option to spawner?
Capistrano defaults to using a spin script that in the documentation
calls spawner to spawn the fcgi or mongrel processes(ref1) . I have
worked on getting apache in conjunction with mongrel to run multiple
rails applications. According to the mongrel documentation you need to
pass the prefix option to mongrel to be able to host multiple rails
applications(ref 2). Spawner did not support the passing of the prefix
option which lead to the creation of this patch.
