(New in Munki 7)

pkginfo items may now contain the key version_script.

The expected value for this key is a string, containing a script that outputs the version number of a currently-installed version of the software, or an empty string (or exits non-zero) if the software is not currently installed. This is a new mechanism Munki can use to determine whether or not an item needs to be installed (or updated). Since it returns a version number, Munki can use its existing version number comparison logic. In most cases, using a version_script (if possible) will be superior to using an installcheck_script.
