Coding Systems
==============

   When Emacs reads or writes a file, and when Emacs sends text to a
subprocess or receives text from a subprocess, it normally performs
character code conversion and end-of-line conversion as specified by a
particular "coding system".

   How to define a coding system is an arcane matter, and is not
documented here.
