salty-ircd aims to be fully compliant with the IRC RFCs (in 'RFC mode'), specifically [RFC 1459](https://tools.ietf.org/html/rfc1459), [RFC 2811](https://tools.ietf.org/html/rfc2811), [RFC 2812](https://tools.ietf.org/html/rfc2812), and [RFC 2813](https://tools.ietf.org/html/rfc2813) (planned), including all errata.
Newer RFCs take precedence over older RFCs.
Any additional features breaking RFC compliance are available through compile-time options.
### Security
The following rules apply when any compile-time option is enabled (breaking strict RFC compliance):
* TLS is required for all connections, except connections from localhost (useful for running a Tor hidden service, which already has encryption)
* TLS client certificates are required for oper and vhost authentication
## Building
Build dependencies:
* A D compiler
* dub
* fish
* git
Build command:
* RFC compliant: `dub build`
* With all additional features: `dub build -c=modern`
TODO: Add a way to supply a custom list of compile-time options.
