# prepare-ci-build.sh
# ============================================================================
# This script prepares the workspace for CI/Docker builds by:
# 1. Switching to Docker-specific workspace configuration
# 2. Installing openvidu-components-angular from npm or tarball
# 3. Installing all dependencies
#
# Usage:
#   ./scripts/prepare-ci-build.sh [options]
#
# Options:
#   --components-angular-version <version>   Install from npm registry (e.g., 3.4.0)
#   --components-angular-tarball <path>          Install from tarball (e.g., ./components.tgz)
#   --help                    Show this help message
#
# Examples:
#   # Install from npm registry
#   ./scripts/prepare-ci-build.sh --components-angular-version 3.4.0
#
#   # Install from tarball
#   ./scripts/prepare-ci-build.sh --components-angular-tarball ./openvidu-components-angular.tgz
#
# See docs/ci-docker-dependencies-strategy.md for more information.
