     * `lock_update`: cargo will want to update `Cargo.lock`.  (The `-u` and `-U` options override this.)
     * `online`: this subcommand makes no sense to run offline.  (The `-o` and `-O` options, and the configuration, can override this.)
     * `edits`: The purpose of this subcommand is to edit the source tree.  Produces warning if `--edit-sources` mode not specified.
+    * `creates`: The purpose of this subcommand is to edit the source tree and create new files in it.  Produces warning if `--edit-sources` (`-E`) mode not specified twice.
     * `!target`: cargo would reject `--target=<arch>`; in this case nailing-cargo's `-T` option is ineffective.
     * `!target-dir`: cargo would reject `--target-dir`, so don't pass it.  (Usually we pass `--target-dir=target` when we pass `--manifest-path`, since cargo's default is `target` in the same directory as `Cargo.toml`.)
     * `linkfarm-shallow`: Make the default be `--linkfarm=shallow`.  This is the default for `miri` and can also be used for other subcommands which do not understandg `--manifest-path` properly.
