# 1. installs uv (https://docs.astral.sh/uv/) if it is missing
# 2. installs the monash command with uv, from PyPI or else from GitHub
# 3. adds uv's tool folder to PATH for new terminals
# 4. starts `monash setup`, unless --no-setup is given or there is no terminal to ask in
#
# It never asks for a password and never touches anything outside uv's own folders.
