+Using Sphinx?
+
+Having trouble writing cross-references?
+
+sphobjinv (short for ‘sphinx objects.inv’) can help!
+
+The syntax required for a functional Sphinx cross-reference is highly non-obvious in many cases. Sometimes Sphinx can guess correctly what you mean, but it’s pretty hit-or-miss. The best approach is to provide Sphinx with a completely specified cross-reference, and that’s where sphobjinv comes in.
