Name
       config - build system configuration files

Syntax
       /etc/config [-p] [-s] config_file

Description
       The  command  builds a set of system configuration files from a short file which describes the sort of system that is being configured.	It
       also takes as input a file which tells what files are needed to generate a system.  This can be augmented by a configuration  specific  set
       of files that give alternate files for a specific machine.  (See the Files section.)  If the -p option is supplied, will configure a system
       for profiling.  You must have sources to use the -p option.  Use the -s option when building a kernel from sources.

       The command should be run from the subdirectory of the system source (usually ).  The command assumes that there  is  already  a  directory
       created	and it places all its output files in there.  The output of consists of a number files: contains a description of what I/O devices
       are attached to the system, and is a file used by in building the system; a set of header files which contain the number of various devices
       that  will  be  compiled into the system; and a set of swap configuration files which contain definitions for the disk areas to be used for
       swapping, the root file system, argument processing, and system dumps.

       After running it is necessary to run in the directory where the new makefile was created.  The command reminds you of  this  when  it  com-
       pletes.

       If  you receive other error messages from fix the errors in your configuration file and try again.  If compile a system that has configura-
       tion errors, the system will fail.

Restrictions
       The line numbers reported in error messages are usually off by one.
