Comma separated list of components like main, contrib and non-free which will
be used for all URI-only I<MIRROR> arguments.
Comma or whitespace separated list of components like main, contrib and
non-free which will be used for all URI-only I<MIRROR> arguments. The option
can be specified multiple times and the components are concatenated in the
order in which they are given on the command line. If later list items are
repeated, then they get dropped so that the resulting component list is free
of duplicates. So the following are equivalent:
--components="main contrib non-free"
--components=main,contrib,non-free
--comp=main --comp="contrib non-free" --comp="main,non-free"
