src/m/README

   1 This directory contains C header files containing machine-specific
   2 definitions.  Each file describes a particular machine.  The emacs
   3 configuration script edits ../config.h to include the appropriate one of
   4 these files, and then each emacs source file includes config.h.
   5
   6 template.h is a generic template for machine descriptions; it
   7 describes the parameters a machine file can specify.
