| 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. | |
