Uru Age Manager
The Uru Age Manager is a sub-tool of Drizzle and, to no surprise, manages the Ages of your Uru: Complete Chronicles installation by downloading, installing, updating and removing them.
Usage
UAM is relatively easy to use: After launching Drizzle, select the "UruAgeManager" tab at the top left of the Drizzle window. Hit the "Select" button next to "Pots folder" and choose the directory you installed Uru to, then hit "Ok". Now you can "Get the latest age list" to download the information about all ages available through Drizzle. If you want that to automatically happen each time you start Drizzle (so you don't miss any age update), you can select the appropriate option at the top right of the window.
Now UAM is set up, and you can browse the list of ages, select whatever you want, and hit "Download" to download the latest version and install or update your installation to use it. To actually reach these ages within Uru, you need the Offline KI, which you can easily install through Drizzle as well: It's at the top of the age list.
Uploading an age
UAM has an upload website which is the easiest way to get an age included. It is however also a good idea to announce this update in the forums, so that Shard owners can pick up the age for their dataservers.
