+WrappedString
+=============
+
+WrappedString is a small PHP library for compacting redundant string-wrapping
+code in text output. The most common use-case is to eliminate redundant runs of
+HTML open/close tags and JavaScript boilerplate.
+
+Here is how you use it:
+
+<pre lang="php">
+use WrappedString\WrappedString;
+
+$buffer = array(
+	new WrappedString( '[foo]', '[', ']' ),
+	new WrappedString( '[bar]', '[', ']' ),
+);
+$output = WrappedString::join( "\n", $buffer );
+// Result: '[foobar]'
+</pre>
