//! FECo3 is a library for parsing .fec files from the US Federal Election Commission.
//!
//! .fec files are binary files that contain campaign finance data.
//! This library provides an efficient, flexible, stream-oriented parser
//! for these files.
//!
//! The parser takes a byte stream as input, which makes it flexible enough
//! to parse files from a variety of sources, including local files, HTTP
//! streams, or a custom source.
//!
//! FECo3 includes a framework for writing the parsed data. Currently,
//! the only supported output format is CSV, but the framework is designed
//! to be extensible to other formats.
//!
//! There are bindings for python available
//! [on the repo](https://github.com/NickCrews/feco3).
