-    Create MBR + EFI boot partition
-
-    This plugin creates a boot partition that contains both
-    legacy BIOS and EFI content. It will be able to boot from both.
-    This is useful when managing PC fleet with some older machines
-    without EFI support.
-
-    Note it is possible to create an image that can boot from both
-    legacy BIOS and EFI by defining two partitions : one with arg
-    --source bootimg-efi  and another one with --source bootimg-pcbios.
-    However, this method has the obvious downside that it requires TWO
-    partitions to be created on the storage device.
-    Both partitions will also be marked as "bootable" which does not work on
-    most BIOS, has BIOS often uses the "bootable" flag to determine
-    what to boot. If you have such a BIOS, you need to manually remove the
-    "bootable" flag from the EFI partition for the drive to be bootable.
-    Having two partitions also seems to confuse wic : the content of
-    the first partition will be duplicated into the second, even though it
-    will not be used at all.
-
-    Also, unlike "isoimage-isohybrid" that also does BIOS and EFI, this plugin
-    allows you to have more than only a single rootfs partitions and does
-    not turn the rootfs into an initramfs RAM image.
-
-    This plugin is made to put everything into a single /boot partition so it
-    does not have the limitations listed above.
-
-    The plugin is made so it does tries not to reimplement what's already
-    been done in other plugins; as such it imports "bootimg-pcbios"
-    and "bootimg-efi".
-    Plugin "bootimg-pcbios" is used to generate legacy BIOS boot.
-    Plugin "bootimg-efi" is used to generate the UEFI boot. Note that it
-    requires a --sourceparams argument to know which loader to use; refer
-    to "bootimg-efi" code/documentation for the list of loader.
-
-    Imports are handled with "SourceFileLoader" from importlib as it is
-    otherwise very difficult to import module that has hyphen "-" in their
-    filename.
-    The SourcePlugin() methods used in the plugins (do_install_disk,
-    do_configure_partition, do_prepare_partition) are then called on both,
-    beginning by "bootimg-efi".
-
-    Plugin options, such as "--sourceparams" can still be passed to a
-    plugin, as long they does not cause issue in the other plugin.
-
-    Example wic configuration:
-    part /boot --source bootimg-biosplusefi --sourceparams="loader=grub-efi"\\
-               --ondisk sda --label os_boot --active --align 1024 --use-uuid
