"""Usage:
  clonemachine.py fork [--unit-e-branch=<name>]
  clonemachine.py file <filename>
  clonemachine.py substitute-unit-e-naming
  clonemachine.py substitute-unit-e-urls
  clonemachine.py substitute-unit-e-executables
  clonemachine.py show-upstream-diff --bitcoin-branch=<name>
  clonemachine.py -h | --help

Commands:
  fork                        Substitute all occurrences of bitcoin specific
                              identifiers by corresponding unit-e identifiers on
                              a fork. Processes files recursively and creates
                              git commits with the changes.
  file                        Do subsitutions on one file. Don't traverse the
                              file tree and don't create git commits.
  substitute-unit-e-naming    Substitute the old unit-e naming scheme by the new
                              one. To be used on the unit-e master branch before
                              merging with a bitcoin version processed through
                              clonemachine using the new naming scheme. Doesn't
                              do git commits. Replaces "UnitE Core" by "unit-e"
                              and "UnitE" by "Unit-e".
  substitute-unit-e-urls      Substitute wrongly subsituted URLs such as to the
                              bitcoin repo or the bips.
  substitute-unit-e-executables  Rename `united` to `unit-e`
  show-upstream-diff          Show how upstream has changed appropriated and
                              removed files since last merge. Requires a
                              `--bitcoin-branch`.

Examples:
  `clonemachine.py --show-upstream-diff --bitcoin-branch upstream/0.17` will
  show the diff from the last merge up to 0.17, provided you have fetched a
  bitcoin remote under the name `upstream`.

Options:
  -h --help                   Show this help
  --unit-e-branch=<name>      Name of unit-e branch [default: master]
  --bitcoin-branch=<name>     Name of bitcoin branch (e.g. bitcoin/master), when
                              this option is set, the diff of appropriated files
                              is shown
