eZ Url Alias Migration Extension

The url alias migration extension is meant to help with retaining run-time
data in the system's url alias table, which cannot automatically be
regenerated after a reset of this table.

This extension will allow you to migrate two types of url aliases, custom url
aliases, and url history elements. The first type are entries which are
manually entered by the user, the latter are automatically generated entries,
which are created when you a user renames objects.
