+// This is a helper class used by ASIHTTPRequest to handle inflating (decompressing) data in memory and on disk
+// You may also find it helpful if you need to inflate data and files yourself - see the class methods below
+// Most of the zlib stuff is based on the sample code by Mark Adler available at http://zlib.net
