-         filesystem for Linux.  It uses zlib compression to compress both
-         files, inodes and directories.  Inodes in the system are very small
-         and all blocks are packed to minimise data overhead. Block sizes
-         greater than 4K are supported up to a maximum of 1 Mbytes (default
-         block size 128K).  SquashFS 4.0 supports 64 bit filesystems and files
-         (larger than 4GB), full uid/gid information, hard links and
-         timestamps.  
-
-         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
-         embedded systems where low overhead is needed.  Further information
-         and tools are available from http://squashfs.sourceforge.net.

-         will be called squashfs.  Note that the root file system (the one
-         containing the directory /) cannot be compiled as a module.
