#!/bin/sh
# install.sh — One-line installer for the openclaw shell wrapper and autocomplete
#
# Run directly from the internet:
#   curl -fsSL https://raw.githubusercontent.com/stritti/clawmetry-docker/main/install.sh | bash
#
# What it installs:
#   1. openclaw.sh   → /usr/local/bin/openclaw  (or ~/.local/bin/openclaw as fallback)
#   2. openclaw_completion.sh → shell-specific location (Bash or Zsh)
#
# Override defaults with environment variables:
#   OPENCLAW_INSTALL_DIR   — directory to install the binary (default: /usr/local/bin)
#   OPENCLAW_REPO          — GitHub repo slug (default: stritti/clawmetry-docker)
#   OPENCLAW_BRANCH        — branch/tag to download from (default: main)
