Name: "loadnef",
Usage: "Load a NEF-consistent script into the VM optionally attaching to it provided signers with scopes",
UsageText: `loadnef [--historic <height>] [--gas <int>] <file> <manifest> [-- <signer-with-scope>, ...]`,
UsageText: `loadnef [--historic <height>] [--gas <int>] <file> [<manifest>] [-- <signer-with-scope>, ...]`,
Flags: []cli.Flag{historicFlag, gasFlag},
Description: `<file> and <manifest> parameters are mandatory.
Description: `<file> parameter is mandatory, <manifest> parameter (if omitted) will
be guessed from the <file> parameter by replacing '.nef' suffix with '.manifest.json'
suffix.
