# Creates and updates the package_version information used by configure.ac |
|
# (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. |

|
# 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. |
