   3 # This script is intended to generate version information for single-file
   4 # products (i.e. things that don't ship in bundles). It takes an input file
   5 # with the suffix ".version" that defines:
   6 #
   7 # DARWIN_BUNDLE_IDENTIFIER
   8 #       The CFBundleIdentifier for the product.
   9 # DARWIN_DISPLAY_NAME
  10 #       The "marketing" name of the product ("Darwin System Bootstrapper" as opposed
  11 #       to "launchd" or "Darwin Kernel" as opposed to "xnu").
  12 # DARWIN_DISPLAY_VERSION
  13 #       The major release version (think "7.0" for iOS 7, "10.9" for Mavericks,
  14 #       etc.).
  15 # DARWIN_INCREMENTAL_VERSION
  16 #       The incremental version (think 12A132, svn revision, project tag, etc.).
  17 # DARWIN_COPYRIGHT
  18 #       The copyright string.
  19 #
  20 # It produces a header (darwin_version.h) that declares:
  21 #
  22 # __darwin_builder_version
  23 #       The integer representation of the version of OS X which built the project
  24 #       (think 1090, 1091, etc.).
  25 # __darwin_builder_build
  26 #       The integer representation of the build of OS X which built the project,
  27 #       represented in hex (think 0x12A132).
  28 # __darwin_build_inc_version
  29 #       A string representation of the given DARWIN_INCREMENTAL_VERSION.
  30 # __darwin_version_string
  31 #       A composed version string which can serve as useful for identifying the
  32 #       version, variant and origin of a given build. It is formatted as:
  33 #
  34 #               $DARWIN_DISPLAY_NAME Version $DARWIN_DISPLAY_VERSION `date`; `whoami`:<objects>
  35 #
  36 #       <objects> is a symbolic link in the OBJROOT pointing to the subdirectory
  37 #       containing the objects for the target being built. The link's name is
  38 #       formatted as:
  39 #
  40 #               ${BASE_PRODUCT_NAME}/${DARWIN_VARIANT}_${UPPER_CASE_CURRENT_ARCH}
  41 #
  42 #       The BASE_PRODUCT_NAME is the first part of the target's PRODUCT_NAME, prior
  43 #       to a '.' character (so the base product name of "launchd.development" is
  44 #       simply "launchd").
  45 #
  46 #       This link points to the appropriate location in the build root. If the SDK
  47 #       being built for is the Simulator, the variant is formatted as:
  48 #
  49 #               ${DARWIN_VARIANT}_SIMULATOR_${UPPER_CASE_CURRENT_ARCH}
  50 #
  51 # It produces an XML Info.plist from this information and embeds it in the
  52 # __TEXT,__info_plist section of the resulting binary.
