+no dependencies.  The main function to parse YAML provided is
+`yaml-parse-string'.  `yaml-encode' is also provided to encode a
+Lisp object to YAML.  The following are some examples of its usage:

+(yaml-parse-string \"key1: value1\
+key2: value2\")
+(yaml-parse-string \"key1: value1\
+key2: value2\" :object-type 'alist)

+(yaml-encode '((count . 3) (value . 10) (items (\"ruby\" \"diamond\"))))
