# --- Main Script ---
# This script presents a menu of software packages defined in a remote
# configuration file. The user can select a package, and the script
# will download the corresponding files. It includes a feature to show
# a diff and ask for confirmation before overwriting existing config files.
# --- Functions ---
# A simple function to log messages with a consistent format.
