+Alternatively, you can also use the `compile()` function to compile the BPF code to an object file:

+```python
+from pythonbpf import compile

+
+This object file can then be loaded using any other userspace library in any language.

 ## Next Example: Tracking Process IDs
 
 Let's make a more interesting program that tracks which processes are being created:
