* Use this in preference to PROJECT_VERSION, with the following exceptions:
* - where a simplified form is expected for compatiblity, for example
* 'udevadm version',
* - where a simplified machine-parsable form is more useful, for example
* pkgconfig files and version information written to binary files.
