|  | # (or other makefiles).  When run inside a git repository it will use the | ||
|  | # version information that can be queried from it unless AUTO_UPDATE is set | ||
|  | # to 'no'.  If no version is currently known it will be set to 'unknown'. | ||
|  | # | ||
|  | # If called with the argument 'release', the PACKAGE_VERSION will be updated | ||
|  | # even if AUTO_UPDATE=no, but the value of AUTO_UPDATE shall be preserved. | ||
|  | # This is used to force a version update whenever `make dist` is run. | ||

|  | # parent directory contains a git repository we do not want to accidentally | ||
|  | # retrieve the version information from it instead.  Tarballs should ship | ||
|  | # with only the package_version file. | ||
