[docs] [issue29062] hashlib documentation link error

INADA Naoki added the comment:

That is because hashlib-blake2.rst is explicitly added to the TOC list in Doc/library/crypto.rst.

Yes. All rst should be explicitly added by `toctree` or `include`. In this case, I feel there are no reason to use `include` directive instead of merging two files. Another option is adding `toctree` directive in `hashlib.rst`. But it means we should organize to use sub toctree, like Doc/library/asyncio.rst. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue29062> _______________________________________
