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.
