-;;; Signatures
-;;; ------------------------------------------------------------------
-;;
-;; From [http://www.last.fm/api/desktopauth]:
-;;
-;; Construct your api method signatures by first ordering all the
-;; parameters sent in your call alphabetically by parameter name and
-;; concatenating them into one string using a <name><value>
-;; scheme. So for a call to auth.getSession you may have:
-;;
-;;   api_keyxxxxxxxxmethodauth.getSessiontokenxxxxxxx
-;;
-;; Ensure your parameters are utf8 encoded. Now append your secret
-;; to this string. Finally, generate an md5 hash of the resulting
-;; string. For example, for an account with a secret equal to
-;; 'mysecret', your api signature will be:
-;;
-;;   api signature = md5("api_keyxxxxxxxxmethodauth.getSessiontokenxxxxxxxmysecret")
-;;
-;; Where md5() is an md5 hashing operation and its argument is the
-;; string to be hashed. The hashing operation should return a
-;; 32-character hexadecimal md5 hash.
