+# The following example creates a zip file with a single entry 
+# <code>log/simplelog.rb</code> that contains a single function 
+# <code>simpleLog</code>: 
+#
+#   require 'zip/zipfilesystem'
+#   
+#   Zip::ZipFile.open("my.zip", true) {
+#     |zf| 
+#     zf.file.open("log/simplelog.rb", "w") {

+#       f.puts '  Kernel.puts "INFO: #{v}"'
+#       f.puts "end"
+#     }
+#   }
+#
+# To use the ruby module stored in the zip archive simply require
+# <code>zip/ziprequire</code> and include the <code>my.zip</code> zip 
+# file in the module search path. The following command shows one
