namespace po = boost::program_options does parse_config_file function support an end-of-line continuation using the backslash character '\' in INI file.   One should be able to specify libraries as follows:   ink_library = tc300c10v10v_hs_levelshifter_worst.db_Tj125_pg \                tc300c10v12v_hs_levelshifter_worst.db_Tj125_pg \   tc300c10v_hs_worst.db_Tj125_pg:tc300c10v_lp_worst.db_Tj125_pg   Similarly, always_on_signals as:   always_on_signals = tb.u_top.uSD_BLK.tmp31,\                          tb.u_top.uSD_BLK.tmp32, \                          tb.u_top.uSD_BLK.out3   Besides readability, we may run into issues due to number of characters per line allowed without support for backslash.   Any help will be appreaciated.   Regards, -mukti __________________________________________________ Do You Yahoo!?
