Mac OS Archive Utilities Bundling Extra Files

When compressing files on the Mac OS into an archive (e.g. zip, tgz etc.), it also includes some hidden files starting with "._". These files contains attributes which are re-applied to the files upon unarchival on another Mac OS system.

However, on other OSes, they appear as real files, which can be really annoying.

To exclude these files:
COPYFILE_DISABLE=1 tar -czvf tarfile.tar.gz <target files>
