Arguments
  [<contract> ...]       Optional list of contract names to compile.

Options:
  --all -a              Recompile all contracts
  --size -s             Show deployed bytecode sizes contracts
  --help -h             Display this message

Compiles the contract source files for this project and saves the results
in the build/contracts/ folder.

Note that Brownie automatically recompiles any changed contracts each time
a project is loaded. You do not have to manually trigger a recompile."""
