| 7 |
* The Pathauto module automatically generates path aliases for various kinds of
|
| 8 |
* content (nodes, categories, users) without requiring the user to manually
|
| 9 |
* specify the path alias. This allows you to get aliases like
|
| 10 |
* /category/my-node-title.html instead of /node/123. The aliases are based upon
|
| 11 |
* a "pattern" system which the administrator can control.
