Instead of using IOptionApplicability.isOptionUsedInCommandLine like
James suggested you can also use IOptionApplicability.isOptionEnabled.
That way, given the above example, you can have otherflag1 and
otherflag2 enabled only if O3 is selected, that means the user can
still check/uncheck them, but only if O3 is selected. Dito for the enum
flags, in case O3 is selected only flag2/flag3 are shown so the user
can still select both of them.
