-	help
-	  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.
-
-	  If unsure, say N.

-config SQUASHFS_EMBEDDED
-
-	bool "Additional option for memory-constrained systems"

-	default n
-	help
-	  Saying Y here allows you to specify cache size.
-
-	  If unsure, say N.
-
-config SQUASHFS_FRAGMENT_CACHE_SIZE
-	int "Number of fragments cached" if SQUASHFS_EMBEDDED
-	depends on SQUASHFS
-	default "3"
-	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.
