Store and restore metadata from a filesystem

 metastore is a tool to store the metadata of files/directories/links in
 a file tree to a separate file and to later compare and apply the
 stored metadata to said file tree.
 .
 The tool was written as a supplement to git which does not store all
 metadata, making it unsuitable for e.g. storing /etc in a repo.
 .
 metastore can also be helpful in a backup script if you want to create
 a tarball of a file tree and make sure that "everything" (e.g. xattrs,
 mtime, owner, group) is stored along with the files.
