Building blocks

Onionspray has the following building blocks:

• Server: or a "machine", is any computer where Onionspray runs -- and you can run it in multiple servers.
• Repository: the Onionspray repository.
• Installation: a working copy of the repository, used to host Onion Service proxies.
• Site: a single Onion Service site that maps a DNS-based domain such as example.org (an optionally all it's subdomains) into an .onion address.
• Project: a project set of sites; each project has it's own instances of C Tor (to run the Onion Services) and OpenResty (for the reverse rewriting proxy).

A server can host many Onionspray installations, each one with many projects, and each project with many sites.
