The package draws ASCII art of animals saying a specified message. The following
macros are available:

 - `\ducksay[<options>]{<message>}`
 - `\duckthink[<options>]{<message>}`
 - `\DefaultAnimal{<animal>}`
 - `\DucksayOptions{<options>}`
 - `\AddAnimal(*){<name>}<ascii-art>`

`<ascii-art>` should be delimited either by matching braces or by the same
symbol and is read verbatim.

Multi-line messages are now fully supported. The package comes with two
versions, choosable with the `version` key.
