+Stub file for a guaranteed safe import of duecredit constructs:  if duecredit
+is not available.
+
+To use it, place it into your project codebase to be imported, e.g. copy as
+
+    cp stub.py /path/tomodule/module/due.py
+
+Note that it might be better to avoid naming it duecredit.py to avoid shadowing
+installed duecredit.
+
+Then use in your code as
+
+    from .due import due, Doi, BibTeX
+
+See  https://github.com/duecredit/duecredit/blob/master/README.md for examples.
