- """A script to prepare version information 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 square 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.
