# This script installs a python3 virtualenv called 'zulip-py3-venv' in zulip's parent directory.
# It then installs mypy and some other dependencies into that virtualenv.
# This script has been written for Ubuntu. If you want to install it on some other distro
# replace these commands with the corresponding commands for your distro.
# (for e.g. on Fedora replace apt-get with yum or dnf)
