+USAGE: $0 BASE_COMMIT TARGET_COMMIT
+
+    BASE_COMMIT:
+        A commit that contains the changes to formatting version and
+        config already from TARGET_COMMIT, but not the automatically
+        applied formatting changes.  Must be the first commit on the
+        branch you are about to rebase (not the one returned by
+        git-merge-base). It will be removed from the resulting branch.
+    TARGET_COMMIT:
+        The commit introducing the formatting that you want to rebase onto.
+
+Rebase a branch onto changes created by an automated formatter. The script
+will keep the (linear) history of the branch intact and make the commits appear
+as if the changes had been applied onto the newly-formatted version all along.
+
+INSTRUCTIONS:
+1. Make a copy of your branch (or be prepared to salvage it from reflog).
+   $ git branch mybranch-backup
+2. Find out what the base commit is.
+3. Rebase onto the base commit yourself.
+   $ git rebase \$BASE_COMMIT
+4. Make sure the formatting tool is installed with the correct version and settings.
+   $ stack install ormolu
+5. Run this script.
+   $ $0 \$BASE_COMMIT \$TARGET_COMMIT

+
+# The general idea is the following:
+#
+# We have a branch consisting of commits C1, C2, ... on top of our BASE_COMMIT C0.
+# Also, from C0 an automated formatting change f was made on some branch (e.g. develop).
+#
+#  C0 ----> C1 ----> C2 ----> ... ----> Cn
+#  |
+#  f
+#  |
+#  v
+#  C0'
+#
+# Now, how do we obtain versions of our commits operating on the formatted code (let's call them Ci')?
+#
+#  C0 ----> C1 ----> C2 ----> ... ----> Cn
+#  |
+#  f
+#  |
+#  v
+#  C0' ---> C1' ---> C2' ---> ... ----> Cn'
+#
+# One useful thing is that since f is defined by an automated tool,
+# we know f applied at every commit Ci, resulting in a hypothetical Ci'.
+#
+#  C0 ----> C1 ----> C2 ----> ... ----> Cn
+#  |        |        |                  |

+#  C0'      C1'      C2'                Cn'
+#
+# And we can also get its inverse g (applied at Ci') by reverting the commit.
+#
+#  C0 ----> C1 ----> C2 ----> ... ----> Cn
