| Some CONFIG options can be implied by others and this can help to reduce |

| each of the x86 defconfig files. |
| |
| This function uses the moveconfig database to find such options. It |

| The algorithm ignores any that start with CONFIG_TARGET since these |
| typically refer to only a few defconfigs (often one). It also does not |
| display a config with less than 5 defconfigs. |
| |
| The algorithm works using sets. For each target config in config_list: |
| - Get the set 'defconfigs' which use that target config |
| - For each config (from a list of all configs): |
| - Get the set 'imply_defconfig' of defconfigs which use that config |
| - |
| - If imply_defconfigs contains anything not in defconfigs then |

| config_list: List of CONFIG options to check (each a string) |
| add_imply: Automatically add an 'imply' for each config. |
| imply_flags: Flags which control which implying configs are allowed |

| latter. In practice this option has not proved very used. |
