Makefile targets

Cargo.toml

ORML use Cargo.dev.toml to avoid workspace conflicts with project cargo config. To use cargo commands in ORML workspace, create Cargo.toml by running

• cp Cargo.dev.toml Cargo.toml, or
• make Cargo.toml, or
• change the command to make dev-check etc which does the copy. (For the full list of make commands, check Makefile)

Web3 Foundation Grant Project
