Viewlet managers for CSS and JavaScript should be ordered

[Douglas Cerna]

There's no way to control the order in which file resources are included.

Regular viewlet managers use this method for sorting viewlets:

-------------------- %< --------------------

    def sort(self, viewlets):
        """Sort the viewlets.

        ``viewlets`` is a list of tuples of the form (name, viewlet).
        """
        # By default, use the standard Python way of doing sorting.
        return sorted(viewlets, lambda x, y: cmp(x[1], y[1]))

-------------------- %< --------------------

which I understand compares the viewlet objects. And as far as I can tell, viewlet objects have no explicit comparison magic methods, right?

Right. You could probably hack something with overriding __cmp__, but don't forget to keep (a > b) == (b < a).

So yes, we do need decent sort control.
