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