33 .Nd system build information
37 contains settings that control the compilation of the
40 and ported applications.
43 is generally created by the system administrator when the values need
44 to be changed from their defaults.
48 is not to run commands or perform compilation actions
50 Instead, it is included by the

57 internal actions according to the settings found there.

64 Options need only be specified in

68 The build procedures occur in four broad areas: the world, the kernel,
69 documentations and ports.
