+//! Support for reading ELF files.
+//!
+//! Traits are used to abstract over the difference between 32-bit and 64-bit ELF.
+//! The primary trait for this is [`FileHeader`].
+//!
+//! ## High level API
+//!
+//! [`ElfFile`] implements the [`Object`](crate::read::Object) trait for ELF files.
+//! [`ElfFile`] is parameterised by [`FileHeader`] to allow reading both 32-bit and
+//! 64-bit ELF. There are type aliases for these parameters ([`ElfFile32`] and
+//! [`ElfFile64`]).
+//!
+//! ## Low level API
+//!
+//! The [`FileHeader`] trait can be directly used to parse both [`elf::FileHeader32`]
+//! and [`elf::FileHeader64`].
+//!
+//! ### Example for low level API
+//!  ```no_run
+//! use object::elf;
+//! use object::read::elf::{FileHeader, Sym};
+//! use std::error::Error;
+//! use std::fs;
+//!
+//! /// Reads a file and displays the name of each symbol.
+//! fn main() -> Result<(), Box<dyn Error>> {
+//! #   #[cfg(feature = "std")] {
+//!     let data = fs::read("path/to/binary")?;
+//!     let elf = elf::FileHeader64::<object::Endianness>::parse(&*data)?;
+//!     let endian = elf.endian()?;
+//!     let sections = elf.sections(endian, &*data)?;
+//!     let symbols = sections.symbols(endian, &*data, elf::SHT_SYMTAB)?;
+//!     for symbol in symbols.iter() {
+//!         let name = symbol.name(endian, symbols.strings())?;
+//!         println!("{}", String::from_utf8_lossy(name));
