442 | It is possible to completely remove a variable or a variable flag | ||
443 | from BitBake's internal data dictionary by using the "unset" keyword. | ||
444 | Here is an example: | ||
445 | <literallayout class='monospaced'> | ||
446 | unset DATE | ||
447 | unset do_fetch[noexec] | ||
448 | </literallayout> | ||
449 | These two statements remove the <filename>DATE</filename> and the | ||
450 | <filename>do_fetch[noexec]</filename> flag. | ||
