  32. """A script to prepare version information for use the gtest Info.plist file.
  33.  
  34.  This script extracts the version information from the configure.ac file and
  35.  uses it to generate a header file containing the same information. The
  36.  #defines in this header file will be included in during the generation of
  37.  the Info.plist of the framework, giving the correct value to the version
  38.  shown in the Finder.
  39.  
  40.  This script makes the following assumptions (these are faults of the script,
  41.  not problems with the Autoconf):
  42.    1. The AC_INIT macro will be contained within the first 1024 characters
  43.       of configure.ac
  44.    2. The version string will be 3 integers separated by periods and will be
  45.       surrounded by square brackets, "[" and "]" (e.g. [1.0.1]). The first
  46.       segment represents the major version, the second represents the minor
  47.       version and the third represents the fix version.
  48.    3. No ")" character exists between the opening "(" and closing ")" of
  49.       AC_INIT, including in comments and character strings.
