The environment variable BUILD_SUMMARY_HEADER can be used to change the default header for the targets' summary table. Extra information can be printed by creating assigning a function to bld.extra_build_summary. That function must receive bld as the first argument and this module as the second one. If one target's task generator (tg) doesn't have a link_task or places the ELF file at a place different from link_task.outputs[0], then tg.build_summary['binary'] should be set as the Node object or a path relative to bld.bldnode for the binary file. Otherwise, size information won't be printed for that target.
