# bot-bottle quick installer.
#
# Usage:
#   curl -fsSL https://gitea.dideric.is/didericis/bot-bottle/raw/branch/main/install.sh | sh
#
# Python-native users can skip this entirely:
#   pipx install bot-bottle        # from a checkout or a published index
#   uv tool install bot-bottle
#
# This script is a thin bootstrapper: it checks prerequisites, installs the
# package with pipx (falling back to pip --user), creates the config dir, and
# runs `bot-bottle doctor`. It is idempotent (safe to re-run) and never uses
# sudo. It does NOT install Docker or a VM backend for you — `doctor` reports
# what's missing after install.
