   3 # This tool is used to stamp kernel version information into files at kernel
   4 # build time.  Each argument provided on the command line is the path to a file
   5 # that needs to be updated with the current verison information.  The file
   6 # xnu/config/MasterVersion is read to determine the version number to use.
   7 # Each file is read, and all occurrences of the following strings are replaced
   8 # in-place like so:
   9 #   ###KERNEL_VERSION_LONG###               1.2.3b4
  10 #   ###KERNEL_VERSION_SHORT###              1.2.3
  11 #   ###KERNEL_VERSION_MAJOR###              1
  12 #   ###KERNEL_VERSION_MINOR###              2
  13 #   ###KERNEL_VERSION_VARIANT###            3b4
  14 #   ###KERNEL_VERSION_REVISION###           3
  15 #   ###KERNEL_VERSION_STAGE###              VERSION_STAGE_BETA  (see libkern/version.h)
  16 #   ###KERNEL_VERSION_PRERELEASE_LEVEL###   4
  17 #   ###KERNEL_BUILDER###                    root
  18 #   ###KERNEL_BUILD_OBJROOT###              xnu/xnu-690.obj~2/RELEASE_PPC
  19 #   ###KERNEL_BUILD_DATE###                 Sun Oct 24 05:33:28 PDT 2004
