# cli-tips Installation Script
# ====================================================================================
#
# This script installs the cli-tips utility and its translations from GitHub.
#
# Installation Process:
#   1. Creates a temporary directory for installation
#   2. Downloads the main executable from GitHub
#   3. Downloads translation files from GitHub repository
#   4. Installs the executable to $PREFIX/usr/bin
#   5. Installs translations to $PREFIX/usr/share/cli-tips/translations
#   6. Cleans up temporary files
#
# Note:
#   - Requires write permissions to $PREFIX directory
#   - Script will exit on first error (set -e)
