+=========
+
+.. current-library:: zlib
+.. current-module:: zlib		     
+
+Utility functions
+-----------------
+
+These functions are implemented on top of the basic zlib
+stream-oriented functions. To simplify the interface, some default
+options are assumed (compression level and memory usage).
+
+
+.. function:: compress
+
+   Compress a string.
+
+   :signature: compress *string* => (compressed-string)
+
+   :parameter string: String to compress. An instance of :drm:`<string>`
+   :value compressed-string: An instance of :drm:`<string>`
+
+   :description:
+
+   Compress the source string into a new string. If there is a problem
+   in the compression process it raises an error.
+
+   :example:
+
+   .. code-block:: dylan
+
+      let compressed = compress("Hello");
