 %description
 Squashfs is a compressed read-only filesystem for Linux. Squashfs is intended for general read-only filesystem use, for archival use (i.e. in cases where a .tar.gz file may be used), and in constrained block device/memory systems (e.g. embedded systems) where low overhead is needed. The filesystem is currently stable, and has been tested on PowerPC, i586, Sparc and ARM architectures.
