# BTW, if 'list-oem' exists, 'list' should not list 'oem' packages. And maybe you should introduce 'list-all'.
# There is another issue where someone reports that --package-list with list-oem is broken
# The dude fixed list-oem, but not list ! How serious is that ?

# There is no 'yolo' file, only 'yolt', related to 'list-oem'.
