<h2>Overview</h2>
<pre id="namespace-docstr">This is a library of string manipulation functions. It
is intented as a replacement for clojure.contrib.str-utils.
You cannot (use 'clojure.contrib.str-utils2) because it defines
functions with the same names as functions in clojure.core.
Instead, do (require '[clojure.contrib.str-utils2 :as s])
or something similar.
Goals:
1. Be functional
2. String argument first, to work with ->
3. Performance linear in string length
Some ideas are borrowed from
<a href="http://github.com/francoisdevlin/devlinsf-clojure-utils/">http://github.com/francoisdevlin/devlinsf-clojure-utils/</a></pre>
