+//! Support for reading Windows COFF files.
+//!
+//! Traits are used to abstract over the difference between COFF object files
+//! and COFF bigobj files. The primary trait for this is [`CoffHeader`].
+//!
+//! ## High level API
+//!
+//! [`CoffFile`] implements the [`Object`](crate::read::Object) trait for
+//! COFF files. [`CoffFile`] is parameterised by [`CoffHeader`].
+//! The default parameter allows reading regular COFF object files,
+//! while the type alias [`CoffBigFile`] allows reading COFF bigobj files.
+//!
+//! [`ImportFile`] allows reading COFF short imports that are used in import
+//! libraries. Currently these are not integrated with the unified read API.
+//!
+//! ## Low level API
+//!
+//! The [`CoffHeader`] trait can be directly used to parse both COFF
+//! object files (which start with [`pe::ImageFileHeader`]) and COFF bigobj
+//! files (which start with [`pe::AnonObjectHeaderBigobj`]).
+//!
+//! ### Example for low level API
+//!  ```no_run
+//! use object::pe;
+//! use object::read::coff::{CoffHeader, ImageSymbol as _};
+//! use std::error::Error;
+//! use std::fs;
+//!
+//! /// Reads a file and displays the name of each section and symbol.
+//! fn main() -> Result<(), Box<dyn Error>> {
+//! #   #[cfg(feature = "std")] {
+//!     let data = fs::read("path/to/binary")?;
+//!     let mut offset = 0;
+//!     let header = pe::ImageFileHeader::parse(&*data, &mut offset)?;
+//!     let sections = header.sections(&*data, offset)?;
+//!     let symbols = header.symbols(&*data)?;
+//!     for section in sections.iter() {
+//!         println!("{}", String::from_utf8_lossy(section.name(symbols.strings())?));
+//!     }
+//!     for (_index, symbol) in symbols.iter() {
+//!         println!("{}", String::from_utf8_lossy(symbol.name(symbols.strings())?));
