elfcpp is a C++ library for reading and writing ELF information. This
was written to support gold, the ELF linker, and may not be generally
useful.
 
elfcpp does not do file I/O. It deals only with offsets and memory
data.
 
For efficiency, most accessors are templates with two arguments: the
ELF file class (32 or 64 bits) and the endianness.

// This header file defines the class Elf_file which can be used to
// read useful data from an ELF file. The functions here are all
// templates which take a file interface object as a parameter. This
// type must have a subtype View. This type must support two methods:
// View view(off_t file_offset, off_t data_size)
// returns a View for the specified part of the file.
// void error(const char* printf_format, ...)
// prints an error message and does not return. The subtype View must
// support a method
// const unsigned char* data()
// which returns a pointer to a buffer containing the requested data.
// This general interface is used to read data from the file. Objects
// of type View will never survive longer than the elfcpp function.
 
// Some of these functions must return a reference to part of the
// file. To use these, the file interface must support a subtype
// Location:
// Location(off_t file_offset, off_t data_size)
// To use this in conjunction with the accessors types Shdr, etc., the
// file interface should support an overload of view:
// View view(Location)
// This permits writing
