Atua: a Gopher Server
-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

Atua is a pair of minimalistic Gopher servers written in Retro. The
primary one handles the gopher0 protocol. The other translates the
gophermaps into html and handles http/0.9.

Features:

- runs via inetd or tcpserver
- written in retro, a forth dialect
- supports simple gophermaps
- supports plain text, images, and simple binary documents

-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

Setting up:

You'll need Retro 12 (get it at forthworks.com/retro). Build this and
put the `rre` binary somewhere.

Take the extracted sources:

 * atua.forth
 * atua-www.forth

And adjust the path to `rre` for your system.

Then, either use tcpserver:

    nohup tcpserver 0 80 ./atua-www.forth &
    nohup tcpserver 0 70 ./atua.forth &

Or add the apropriate entrires for your inetd configuration.
