Deleting the custom package from system

Hello All,

I have created a custom package and added few custom programs.

I have deleted the custom program first, they were deleted successfully.

At last I try to delete the custom package, I am getting a message as "The package still contains subobjects".

But actual all the objects related to package were deleted.

Please let me know how to delete the custom package completely from the system?

Thanks,

Feroz.
