# 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
OLD=machine.h
NEW=new_machine.h
# Save optional dialect directory.

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.
