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