//! Romulus is a text processing language similar to sed
//!
//! Here is an example program which process the output of ifconfig
//! ```text
//! /^(?P<inter>[a-zA-Z0-9]+): /,/^[a-zA-Z0-9]+:/ {
//!   /inet (?P<ip>[0-9]{1,3}(\.[0-9]{1,3}){3})/ {
//!     print("${inter}: ${ip}")
//!   }
//!
//!   /inet6 (?P<ip>[a-fA-F0-9]{0,4}(:[a-fA-F0-9]{0,4}){0,8})/ {
//!     print("${inter}: ${ip}")
//!   }
//! }
//! ```
