The Common Gateway Interface for Gemini
The Common Gateway Interface can easily be adapted for the new Gemini
protocol. In fact, the document you are reading right now is genreated from
a program via the Common Gateway INterface, aka CGI. The specification for
CGI, RFC-3875, is pretty straightforward, and if you strip out the HTTP
specific bits, it was rather easy to implement.
