" The program is not exhaustive, and only encapsulates detailed knowledge of a\r\n"\r
" limited number of table types.\r\n"\r
" \r\n"\r
" Default behaviour is to display the content of all tables installed.\r\n"\r
" 'Known' table types (listed in NOTES below) will be parsed and displayed\r\n"\r

" Other table types will be displayed as an array of Hexadecimal bytes.\r\n"\r
" \r\n"\r
" To facilitate debugging, the -s and -d options can be used to generate a\r\n"\r

" 1. The AcpiTable parameter can match any installed table type.\r\n"\r
" 2. -s option supports to display the specified AcpiTable type that is present\r\n"\r
" in the system. For normal type AcpiTable, it would display the data of the\r\n"\r
