13: .I Config
14: is a tool used in building 4.3BSD system images (the UNIX kernel).
15: It takes a file describing a system's tunable parameters and
16: hardware support, and generates a collection
17: of files which are then used to build a copy of UNIX appropriate
18: to that configuration.
19: .I Config
20: simplifies system maintenance by isolating system dependencies
21: in a single, easy to understand, file.
22: .PP
23: This document describes the content and
24: format of system configuration
25: files and the rules which must be followed when creating
26: these files. Example configuration files are constructed
27: and discussed.
28: .PP
29: Later sections suggest guidelines to be used in modifying
30: system source and explain some of the inner workings of the
31: autoconfiguration process. Appendix D summarizes the rules
32: used in calculating the most important system data structures
33: and indicates some inherent system data structure size
34: limitations (and how to go about modifying them).
