+    This is a one-off / one-time cleanup script for release entities, to fix
+    upper-case DOIs. In fatcat, all DOIs should be normalized to lowercase.
+
+    While this calls itself a cleanup, it is based on the import code path. It
+    is not integrated into the `fatcat_import` or `fatcat_cleanup` controller;
+    instead it has a __main__ function and is invoked like:
+
+        python -m fatcat_tools.cleans.release_lowercase_doi - < blah.tsv
+
+    It expects to get a simple text line on stdin, which is a release entity.
+    The correction is implemented by fetching the current version of the
+    entity, verifying the issue, and updating if it is still a problem.
+
+    This does not try to do any merging, just corrects the case in a single
+    update.
