* This script is for upgrading from 1.3.2 -> 1.4.0. |

* This script will convert Smarty variable references from the old format to |
| 6 |
* the new one. For example, what used to look like $section1/foo.bar will now |
| 7 |
* be $foo[section1].bar. This allows for more readable syntax and also allows |
| 8 |
* referencing deeply nested structures of arbitrary complexity. |
