+This test is here to ensure that the very minimal API we provide to ensure
+users can eventually custromize the order of global transformations (i.e.
+structure -> structure and signature -> signature) does work as intended.
+
+For this test we have two different ppx-es: exp_to_a and exp_to_b which both
+rewrite the same [%exp] into either a or b.
+
+We have two different drivers, both of them have both ppx-es linked but one
+reorders transformations to ensure exp_to_a is first in the list and the other
+that exp_to_b is first.
+
+If we consider the following ml file:
+
+  $ cat > test.ml << EOF
+  > let x = [%exp]
+  > EOF
+
+If we run the driver with exp_to_a first:
+
+  $ ./driver_a_first.exe test.ml
+  let x = a
+
+And the one with exp_to_b first:
+
+  $ ./driver_b_first.exe test.ml
+  let x = b
