If attribute/s is/are already enabled (by default or via scripts or
manual interaction), issuing -a will fail to enable the channels thereby
one has to manually disable the said attribute/s before proceeding with
auto-enabling.
Add a command-line option -A to force-activate all channels regardless
of their current state.
