All contracts are deployed by the committee, so access to the alphabet wallets is required.
Optionally, arguments can be provided to be passed to a contract's _deploy function.
The syntax is the same as for 'neo-go contract testinvokefunction' command.
Compiled contract file name must contain '_contract.nef' suffix.
Contract's manifest file name must be 'config.json'.
NNS name is taken by stripping '_contract.nef' from the NEF file (similar to neofs contracts).`,
