# Dependencies derive from PyPI's info.requires_dist for this exact release
# (the old ebuild's RDEPEND dated from 1.22.0; between then and 1.66.0
# upstream dropped Tornado for a Starlette+Uvicorn backend, which pulls in
# a mostly different dependency set -- GitPython, python-dateutil, semver,
# toml, validators, blinker, cachetools, importlib-metadata, pympler,
# tornado and tzlocal are gone; starlette, uvicorn, anyio,
# python-multipart, websockets and itsdangerous are new).
#
# Note that:
# * Streamlit tarballs currently contain *NO* documentation or tests. /shrug/
# * Streamlit itself is housed under the "lib/" subdirectory of the official
#   Streamlit GitHub repository at:
#       https://github.com/streamlit/streamlit/tree/develop/lib
