+zlib to compress files, inodes, and directories.  All blocks are packed to
+minimize the data overhead, and block sizes of between 4K and 1M are supported.
+It is intended to be used for archival use, for live CDs, and for embedded
+systems where low overhead is needed.  This package allows you to create and
+extract such filesystems.")
