gopher-proxy allows to proxy gopher over HTTP, which is mainly useful for HTTP-ifying a specific gopher space.
A simple invocation looks like this:
In this particular example gopher-proxy does the following things:
Takes HTTP requests on 127.0.0.1:8080 (to be used by a proxying web server, like nginx), converts those to gopher requests to example.org and returns the gopher responses as HTTP responses
Links menu items pointing to external servers to gopher:// URLs (this ensures that only one gopher server is proxied) and recognizes URL links which are converted to normal HTML links
Tries to guess the correct mime-type for every gopher-served file (as it is not included in the response) and wraps text files in a HTML container.
And generally works hard to offer the best HTTP equivalent of a given gopher space :)
