| 8 | This folder contains several examples of Logtalk programs. Most of |
|---|
| 9 | these examples need objects, protocols and categories that are |
|---|
| 10 | defined in the Logtalk standard library or in other examples, so |
|---|
| 11 | you should load them first (see the NOTES file inside each example |
|---|
| 12 | folder). |
|---|
| 13 | |
|---|
| 14 | Some examples may redefine objects already loaded from other examples. |
|---|
| 15 | You may want to restart Logtalk after trying each example. |
|---|
| 16 | |
|---|
| 17 | Some of the examples code have been adopted from public available |
|---|
| 18 | Prolog code and from known Prolog text books and are copyrighted by |
|---|
| 19 | the respective authors. |
|---|
| 20 | |
|---|
| 21 | These are programming examples, meaning that you should look at the |
|---|
| 22 | source files to fully understand them. |
|---|
| 23 | |
|---|
| 24 | All examples are formatted using four spaces tabs. |
