#!/bin/bash
# Script to migrate mmg and parmmg packages from their individual components to the base component
#
# This script leverages the feelpp-aptly-publisher Python package which automatically:
# - Recovers aptly database from existing publications
# - Preserves existing components when adding/updating
# - Republishes all components together
#
# The migration simply republishes packages using the updated scripts that target 'base' component.
