Generate test cases like this:

	$ ./generate_testcases.sh

Test a specific case like that:

	$ ./check.sh source pkgc:i386 none all none allowed depends pkgb:any

Check all cases:

	$ ./generate_testcases.sh | while read a b c d e f g h; do ./check.sh $a $b $c $d $e $f $g $h 2>/dev/null; done

Or in parallel:

	$ ./generate_testcases.sh | xargs --max-procs=8 --max-args=8 ./check.sh 2>/dev/null
