Add `source' and `build' directives, and corresponding options, per discussion

on tech-kern.  (See man page.)  Implementation by Greg Hudson.
Also, remove special case for i386 in vector handling, although this code isn't
actually used any more.

-This is the new version of the

+.Ar config-file ,
+which describes the system to configure.
+.Pp
+There are several different ways to run the
 .Nm config
-program.
-.\"It understands the more modern autoconfiguration scheme
-.\"used on the SPARC and i386 platforms.
-.\"The old version of config is still used with the

+and so forth), and to specify as the
+.Ar config-file
+the name of a file located in that directory.
+.Nm config
+will by default create files in the directory
+.Pa ../compile/SYSTEMNAME ,
+where
+.Pa SYSTEMNAME
+is the last path component of
+.Ar config-file .
 .Nm Config
-assumes the directory

-creating the subdirectory if necessary.
-The subdirectory name is taken from the
-.Ar system-name ;
-thus, configuring with
-.Dq Li config PICKLE
-will use the directory
-.Pa ../compile/PICKLE .
+will assume that the top-level kernel source directory is located four
+directories above the build directory.
+.Pp
+Another way is to create the build directory yourself, place the
+configuration file in the build directory with the name
+.Pa CONFIG ,
+and run
+.Nm config
+from within the build directory without specifying a
+.Ar config-file .
+.Nm Config
+will then by default create files in the current directory.  If you
+run
+.Nm config
+this way, you must specify the location of the top-level kernel source
+directory using the
+.Fl s
+option or by using the
+.Dq Li source
+directive at the beginning of the system configuration file.
+.Pp
+Finally, you can specify the build directory for
+.Nm config
+and run it from anywhere.  You can specify a build directory with the
+.Fl b
+option or by using the
+.Dq Li build
+directive at the beginning of the system configuration file.  You must
+specify the location of the top-level kernel source directory if you
+specify a build directory.
 .Pp
 If the
 .Fl p
 option is supplied,
 .Pa .PROF
-is appended to the compilation directory name, and
+is appended to the default compilation directory name, and
 .Nm config
 acts as if the lines
