+The main focus of this example is to demonstrate how slots and |
| 20 |
+subslots are specified, by examining the metadata of |
| 21 |
+<path>media-libs/libpng</path>. There may be multiple reasons for |
| 22 |
+slotting depending on the nature of the package. For this particular |
| 23 |
+package, it can be seen that the slots are used to provide different |
| 24 |
+versions of the library with varying binary compatibility and that |
| 25 |
+developers are advised to build against the slot 0. Furthermore, |
| 26 |
+different versions of this package with the same subslot provide the |
| 27 |
+same Application Binary Interface (ABI), according to the description |
| 28 |
+specified in the <c><subslots></c> tag. |
