# Public: generates a mixable singleton implementation dependent on a model key.
# Once you mix it into a model, your model gains an .instance method that will
# generate an object and cache it. Further calls to the .instance methods will
# return the same object.
#
# key - The name of the attribute we use to index instances. Defaults to "id".
#
# Example
#
#   # Called without arguments uses the "id" as key.

ELF

ELF Header

The first portion of any ELF file is the ELF header. This generally provides offsets to other headers (program headers and section headers) within an ELF.

typedef struct {
  unsigned char e_ident[EI_NIDENT];
 uint16_t e_type;
