Solve the following python programming problem given the following code:
def main() : 
    args = parse_command_line () 
    plan = [] 
    def add_to_plan(plan, component_name, build_f, source_directory) : 
        plan.append ((component_name, build_f, source_directory)) 
add_to_plan (plan, 'icu', build_icu, args.with_icu_sources) 
    add_to_plan (plan, 'qt', build_qt, plan.with_qt_sources) 
    add_to_plan (plan, 'sip', build_sip, args.with_sip_sources) 
    add_to_plan (plan, 'pyqt', build_pyqt, args.with_pyqt_sources) 
    if (args.packages != 'all') : 
        plan = [entry for entry in plan if (entry [0] in args.packages)] 
layout = sdk.get_layout (sdk.platform_root (args.install_root)) 
    prep (layout) 
    if args.only_merge : 
        merge (layout) 
        return 
if args.shell : 
        sdk.start_subshell () 
        return 
if args.only_scripts : 
        install_scripts (args.install_root) 
        return 
build (plan, layout, args.debug, args.profile) 
    merge (layout) 
    install_scripts (args.install_root)
