| 16 | """Generates TypeScript files that import all subdirectories. |
| 17 | This is useful for plugins/extensions. If you have two modules: |
| 18 | - core/ |
| 19 | - plugins/myplugin/ |
| 20 | In general you would like the dependency to only go one way: |
| 21 | - plugins/myplugin/ -> core/ |
| 22 | But you still need some index file to import all plugins for the sake of |
| 23 | bundling. This avoids having to manually edit core/ for every |
| 24 | plugin you add. |
