# -- Path setup --------------------------------------------------------------

# If extensions (or modules to document with autodoc) are in another directory,
# add these directories to sys.path here. If the directory is relative to the
# documentation root, use os.path.abspath to make it absolute, like shown here.

# Hack to get crosslinks working where things are available (and referred to) by
# several paths. E.g. we export rx.Observable but that's not its fully qualified
# name, and this causes the automatically generated links to fail for the
# argument / return types of functions (e.g. as defined in rx/__init__.py).
#
# It looks as though the intention of sphinx_autodoc_typehints is to include
# support for something like this in a future version:
