michael@0: """A script to prepare version informtion for use the gtest Info.plist file.
michael@0: 
michael@0:   This script extracts the version information from the configure.ac file and
michael@0:   uses it to generate a header file containing the same information. The
michael@0:   #defines in this header file will be included in during the generation of
michael@0:   the Info.plist of the framework, giving the correct value to the version
michael@0:   shown in the Finder.
michael@0: 
michael@0:   This script makes the following assumptions (these are faults of the script,
michael@0:   not problems with the Autoconf):
michael@0:     1. The AC_INIT macro will be contained within the first 1024 characters
michael@0:        of configure.ac
michael@0:     2. The version string will be 3 integers separated by periods and will be
michael@0:        surrounded by squre brackets, "[" and "]" (e.g. [1.0.1]). The first
michael@0:        segment represents the major version, the second represents the minor
michael@0:        version and the third represents the fix version.
michael@0:     3. No ")" character exists between the opening "(" and closing ")" of
michael@0:        AC_INIT, including in comments and character strings.
