+    * pluralize
+    *
+    * pluralize is a handlebar helper that handles pluralization of strings.
+    * The requirement for pluralization is based on the passed in object,
+    * which can be number, array, or object. If a number, it is directly
+    * checked to see if pluralization is needed. Arrays and objects are
+    * checked for length or size attributes, which are then used.
+    *
+    * By default, if pluralization is needed, an 's' is appended to the
+    * string. This handles the regular case (e.g. cat => cats). Irregular
+    * cases are handled by passing in a plural form (e.g. octopus => ocotopi).

Good thinking, plurals are very hard to do automatically.
