The original description in README.md is
This tool is to convert a default Lock(SECP256K1/blake160) to quantum resistant lock script..
It sounds like to create a new lock script from existing lock script, but after look at the code, it's real purpose is to consume a default lock(SECP256K1/blake160) protected cell and create a quantum resistant lock script lock protected cell.
So I think it's better to make it more clear.
