Currently all download helpers accepts the local output file, the remote locations, the changesets and so on... as positional arguments. This was well and nice when that's was all we needed. But then we added an option to quiesce their verbosity, and that was shoehorned with a trivial getopts, still keeping all the existing positional arguments as... positional arguments. Adding yet more options while keeping positional arguments will not be very easy, even if we do not envision any new option in the foreseeable future (but 640K ought to be enough for everyone, remember? ;-) ). Change all helpers to accept a set of generic options (-q for quiet and -o for the output file) as well as helper-specific options (like -r for the repository, -c for a changeset...). Maxime: Changed -R to -r for recurse (only for the git backend) Changed -r to -u for URI (for all backend) Change -R to -c for cset (for CVS and SVN backend) Add the export of the BR_BACKEND_DL_GETOPTS so all the backend wrapper can use the same option easily Now all the backends use the same common options.
