+# Customize: customize dialect's machine.h header file.
+#
+# Allows easy modification of some important compile-time definitions for
+# lsof, made in the dialect's machine.h header file, including:
+#
+#	HASSECURITY	the security option
+#	HASNOSOCKSECURITY
+#			the socket oberalization of HASSECURITY
+#	HASDCACHE	enabling/disabling the device cache file
+#			(Note: changing the device cache file option isn't
+#			       offered when machine.h contains NEVER_HASDCACHE
+#			       anywhere, including in a comment.)
+#	HASENVDC	enabling/disabling device cache path from environment
+#	HASKERNIDCK	enabling/disabling the kernel identity check
+#			(not done for some dialects)
+#	HASPERSDC	enabling/disabling personal device cache path
+#			construction
+#	HASPERSDCPATH	enabling/disabling additional personal device cache
+#			path component
+#	HASSYSDC	enabling/disabling system-wide device cache file path
+#	HASXOPT_ROOT	enabling/disabling root use of the -X option
+#	WARNDEVACCESS	enabling inaccessible /dev node warnings
+#			(Note: changing the inaccessible /dev/node warning
+#			       option isn't offered when machine.h contains
+#			       NEVER_WARNDEVACCESS anywhere, including in a
+#			       comment.)
+#	WARNINGSTATE	enable/disabling default warning message state
+#
+# Usage: Customize [dialect_directory]
+#
+# where: dialect_directory (optional) is the directory in which the dialect's
+#	 dialect's sources, Makefile and scripts are found

+You may now customize the machine.h header file for this UNIX
+dialect.  The customizations will take effect when you compile
+lsof.  You may also choose to skip customization and proceed to
+the compilation of lsof.
+
+If you don't know if you need to customize or want to know more
+about what you can customize, consult the 00DCACHE, 00FAQ, 00PORTING,
+and 00README files of the lsof distribution.  You might also find
+it helpful to examine the machine.h header file for the dialect
+you're customizing.
+
+You don't need to use this procedure to customize lsof; you can
+edit the machine.h header file directly.  If you later decide you
+want to use this procedure to customize machine.h, execute the
+./Customize script.
