+  module Benchmarkable
+    # Allows you to measure the execution time of a block 
+    # in a template and records the result to the log. Wrap this block around
+    # expensive operations or possible bottlenecks to get a time reading
+    # for the operation.  For example, let's say you thought your file 
+    # processing method was taking too long; you could wrap it in a benchmark block.
+    #
+    #  <% benchmark "Process data files" do %>
+    #    <%= expensive_files_operation %>
+    #  <% end %>
+    #
+    # That would add something like "Process data files (345.2ms)" to the log,
+    # which you can then use to compare timings when optimizing your code.
+    #
+    # You may give an optional logger level as the :level option.
+    # (:debug, :info, :warn, :error); the default value is :info.
+    #
+    #  <% benchmark "Low-level files", :level => :debug do %>
+    #    <%= lowlevel_files_operation %>
+    #  <% end %>
+    #
+    # Finally, you can pass true as the third argument to silence all log activity 
+    # inside the block. This is great for boiling down a noisy block to just a single statement:
+    #
+    #  <% benchmark "Process data files", :level => :info, :silence => true do %>
+    #    <%= expensive_and_chatty_files_operation %>
