Usage

1. Launch the application. It will automatically start to download the Zoo pages. You can refresh the contents anytime later. Please make sure that your iPad can reach the Zoo server.
   • Downloaded pages include Symbols, A,B,…, Z, and References. You should be able to view them offline.
2. Then, select a complexity class from the index and you will see the description.
   • If you select a class A, you will see not only A but also all other classes having links to A.
3. If you click a reference like [Tod89], a dialog will show up.
4. When you download an update, please refresh the Zoo contents by clicking the refresh button at the left bottom corner of the Index view.

Known Issues

• Some class names in the Index view are not correctly displayed. E.g., <sub> and <sup> tags are not supported.
• If the HTML syntax of Zoo pages changes, the application will not work.
