This library provides improved handling for Clojure functions with optional parameters. The library provides the macro defn+opts which defines a function with optional parameters. The syntax is similar to the one of Clojure's defn except that only one function body is allowed.

A documentation string for optional parameters is supported. When a defn+opts function f calls another defn+opts function g and passes its options symbol then the docstring of f will contain information about the optional parameters that can be passed to g.
