I assume you mean doing this at the REPL or OS shell. I don't know how
to do it for non-loaded libs, aside from manually walking the classpath,
but (all-ns) might be what you want for loaded namespaces.
Usually I just look at the documentation or the source code of the
library (eg. unzip -l clojure-contrib.jar | grep 'clj$').

There's some useful functions in clojure.contrib.ns-utils for printing
documentation, for example:
(use 'clojure.contrib.ns-utils)
(docs clojure.xml)
If you literally just wanted a list of all the functions in a namespace.
then (ns-publics 'some.namespace) will give you a map of all the vars in
the namespace. You could then just filter the ones that are functions.
So something like:
(defn ns-functions [ns]
(for [[n, v] (ns-publics ns)
:when (and (.isBound v)
(instance? clojure.lang.Fn @v))]
n))
(ns-functions 'clojure.xml)
=> (startparse-sax parse emit-element emit)
Cheers,
Alex
