'meta' is the filename of the meta file in the package. In some cases (i.e. a rebuild of the full area) we want to add multiple packages, so we have multiple meta files in that case. To speed things up, some data about the meta file is cached, e.g. the md5sum. To see if the cache is valid, we set 'lastmeta' to the current meta file.
