+          Saying Y here includes support for SquashFS 4.0 (a Compressed
+          Read-Only File System).  Squashfs is a highly compressed read-only
+          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.
+
+          If you want to compile this as a module ( = code which can be
+          inserted in and removed from the running kernel whenever you want),
+          say M here and read <file:Documentation/modules.txt>.  The module
+          will be called squashfs.  Note that the root file system (the one
+          containing the directory /) cannot be compiled as a module.

+        help
+          By default SquashFS caches the last 3 fragments read from
+          the filesystem.  Increasing this amount may mean SquashFS
+          has to re-read fragments less often from disk, at the expense
+          of extra system memory.  Decreasing this amount will mean
+          SquashFS uses less memory at the expense of extra reads from disk.
+
+          Note there must be at least one cached fragment.  Anything
+          much more than three will probably not make much difference.
