<pre>
(ns your-namespace

</pre><pre>
</pre><h2>Overview</h2>
<pre id="namespace-docstr">Simple code profiling &amp; timing measurement.

Wrap any section of code in the prof macro, giving it a name, like this:

       (defn my-function [x y]
         (let [sum (prof :addition (+ x y))
               product (prof :multiplication (* x y))]
           [sum product]))

The run your code in the profile macro, like this:

       (profile (dotimes [i 10000] (my-function 3 4)))

Which prints a report for each named section of code:

          Name      mean       min       max     count       sum
      addition       265         0     37000     10000   2655000
multiplication       274         0     53000     10000   2747000

Times are measured in nanoseconds, to the maximum precision available
under the JVM.  See the function documentation for more details.</pre>
