+	Cramfs - cram a filesystem onto a small ROM
+
+cramfs is designed to be simple and small, and to compress things well. 
+
+It uses the zlib routines to compress a file one page at a time, and
+allows random page access.  The meta-data is not compressed, but is
+expressed in a very terse representation to make it use much less
+diskspace than traditional filesystems. 
+
+You can't write to a cramfs filesystem (making it compressible and
+compact also makes it _very_ hard to update on-the-fly), so you have to
+create the disk image with the "mkcramfs" utility in scripts/cramfs.
