     32 """A script to prepare version informtion 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 squre 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.
