| 588 | Below is a list of `Form'/`Face' pairs. When deciding how a a |
| 589 | particular group line should be displayed, each form is |
| 590 | evaluated. The content of the face field after the first true form is |
| 591 | used. You can change how those group lines are displayed by |
| 592 | editing the face field. |
| 593 | |
| 594 | It is also possible to change and add form fields, but currently that |
| 595 | requires an understanding of Lisp expressions. Hopefully this will |
| 596 | change in a future release. For now, you can use the following |
| 597 | variables in the Lisp expression: |
| 598 | |
| 599 | group: The name of the group. |
| 600 | unread: The number of unread articles in the group. |
