# Note that a live git-managed "9999" version is intentionally *NOT* provided.
# This Python package is embedded in a larger JavaScript "deck.gl" package,
# significantly complicating installation from the GitHub repository. See also:
#     https://github.com/visgl/deck.gl/tree/master/bindings/pydeck

#FIXME: pydeck's "setup.py" appears to be improperly configured and is currently
#emitting Gentoo QA warnings. Although they appear to all be fairly ignorable,
#submit an upstream deck.gl issue requesting an upstream resolution.
#FIXME: pydeck's "setup.py" also provides a facility for building a widget
#frontend (whatever that is). Sadly, doing so appears extremely non-trivial;
#indeed, it's unclear whether the published source tarball supports building
#this frontend, as doing so appears to require the full deck.gl git repository.
