+`format` can also be used to format entire source files and display them on a page. Simply put an [[inline]] directive with the `raw` attribute set inside a `format`. This can be useful if you want to both serve the file raw, as well as show it syntax highlighted on a page. An example:
+
+       \[[!format python """
+       [[!inline pages="program.py" raw="yes"]]
+       """]]
