+INTRODUCTION
+.PP
+.I Config
+is a tool used in building 4.4BSD system images (the UNIX kernel).
+It takes a file describing a system's tunable parameters and
+hardware support, and generates a collection
+of files which are then used to build a copy of UNIX appropriate
+to that configuration.
+.I Config
+simplifies system maintenance by isolating system dependencies
+in a single, easy to understand, file.
+.PP
+This document describes the content and
+format of system configuration
+files and the rules which must be followed when creating
+these files. Example configuration files are constructed
+and discussed.
+.PP
+Later sections suggest guidelines to be used in modifying
+system source and explain some of the inner workings of the
+autoconfiguration process. Appendix D summarizes the rules
+used in calculating the most important system data structures
+and indicates some inherent system data structure size
+limitations (and how to go about modifying them).
