+.Sh NAME
+.Nm config.new
+.Nd build kernel compilation directories
+.Sh SYNOPSIS
+.Nm config
+.Op Fl p
+.Ar system-name
+.Sh DESCRIPTION
+.Pp
+This is the new version of 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
+HP300, DECstation, and derivative platforms.
+Only the version of 
+.Nm config
+applicable to the architecture that you are running
+will be installed on your machine.
+.Pp
+.Nm Config
+builds a set of configuration files from the file
+.Ar system-name ,
+which describes
+the system to configure.
+.Pp
+.Nm Config
+should run from the
+.Pa conf
+subdirectory of the top-level machine-specific directory
+of the system source (usually
+.Pa /sys/MACHINE/conf ,
+where
+.Pa MACHINE
+is one of
+.Pa vax ,
+.Pa tahoe ,
+.Pa hp300 ,
+and so forth).
+.Nm Config
+assumes the directory
+.Pa ../../compile
+exists; it places all output files in a subdirectory there,
+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 .
+.Pp
+If the
+.Fl p
+option is supplied,
+.Pa .PROF
+is appended to the compilation directory name, and
+.Nm config
+acts as if the lines
+.Dq Li makeoptions PROF="-pg"
+and
+.Dq Li options GPROF
+appeared in the configuration file.
+This will build a system that includes profiling code; see
+.Xr kgmon 8
+and
+.Xr gprof 1 .
+The
+.Fl p
+flag is expected to be used for
+.Dq one-shot
+profiles of existing systems;
+for regular profiling,
+it is probably wiser to make a separate configuration
+containing the
+.Li makeoptions
+line.
+.Pp
+The old undocumented
+.Fl g
+flag is no longer supported.
+Instead, use
+.Dq Li makeoptions DEBUG="-g"
+and (typically)
+.Dq Li options KGDB .
+.Pp
+The output of
+.Nm config
+consists of a number of files, principally
+.Pa ioconf.c ,
+a description of I/O devices that may be attached to the system; and a
+.Pa Makefile ,
+used by
+.Xr make 1
+in building the kernel.
+.Pp
+After running
+.Nm config ,
+it is wise to run
+.Dq Li make depend
+in the directory where the new makefile
+was created.
+.Nm Config
+prints a reminder of this when it completes.
+.Pp
+If
+.Nm config
+stops due to errors, the problems reported should be corrected and
+.Nm config
+should be run again.
+.Nm Config
+attempts to avoid changing the compilation directory
+if there are configuration errors,
+but this code is not well-tested,
+and some problems (such as running out of disk space)
+are unrecoverable.
