@ -181,6 +181,7 @@ Available extended configuration parameters:
| `force` | Force removes the old target, file or folder, and forces a new link (default:false) |
| `relative` | Use a relative path when creating the symlink (default:false, absolute links) |
| `glob` | Treat a `*` character as a wildcard, and perform link operations on all of those matches (default:false) |
| `ignore-missing` | Do not fail if the source is missing and create the link anyway (default:false) |
#### Example
