-//! Support for reading PE files.
-//!
-//! Traits are used to abstract over the difference between PE32 and PE32+.
-//! The primary trait for this is [`ImageNtHeaders`].
-//!
-//! ## High level API
-//!
-//! [`PeFile`] implements the [`Object`](crate::read::Object) trait for
-//! PE files. [`PeFile`] is parameterised by [`ImageNtHeaders`] to allow
-//! reading both PE32 and PE32+. There are type aliases for these parameters
-//! ([`PeFile32`] and [`PeFile64`]).
-//!
-//! ## Low level API
-//!
-//! The [`ImageNtHeaders`] trait can be directly used to parse both
-//! [`pe::ImageNtHeaders32`] and [`pe::ImageNtHeaders64`].
-//!
-//! ### Example for low level API
-//! ```no_run
-//! use object::pe;
-//! use object::read::pe::ImageNtHeaders;
-//! use std::error::Error;
-//! use std::fs;
-//!
-//! /// Reads a file and displays the name of each section.
-//! fn main() -> Result<(), Box<dyn Error>> {
-//! # #[cfg(feature = "std")] {
-//! let data = fs::read("path/to/binary")?;
-//! let dos_header = pe::ImageDosHeader::parse(&*data)?;
-//! let mut offset = dos_header.nt_headers_offset().into();
-//! let (nt_headers, data_directories) = pe::ImageNtHeaders64::parse(&*data, &mut offset)?;
-//! let sections = nt_headers.sections(&*data, offset)?;
-//! let symbols = nt_headers.symbols(&*data)?;
-//! for section in sections.iter() {
-//! println!("{}", String::from_utf8_lossy(section.name(symbols.strings())?));
-//! }
-//! # }
-//! Ok(())
-//! }
-//! ```
