+[CodeRay][1] filter for [Haml][2]. Specify [language][3] to highlight
+with an exclamation point followed by the language name:
+
+    :coderay
+      !ruby
+
+      if true
+        puts "hello"
+      end
+
+    :coderay
+      !xml
+
+      <foo>
+        <bar>...</bar>
+      </foo>
+
+The default encoder and encoder options are `:div` and `{}`,
+repectively, and are accessible through the following variables:
+
+    Haml::Filters::CodeRay.encoder
+    Haml::Filters::CodeRay.encoder_options
