This package registers the prototype javascript library as a browser
resource called `prototype.js`.
+Additionally if zc.resourcelibrary is installed it also registers a
+resourcelibrary called 'z3c.javascript.prototype'.
+
See: http://prototype.conio.net/
Note: This package is always kept in sync with the script.aculo.us
library requirements which is provided by the
``z3c.javascript.scriptacoulus`` package
