 This will need to be re-ran any time the binary is rebuilt and can be automated by adding the ''setcap'' target to your ''make'' command-line executed in ''src/sbbs3'': This will need to be re-ran any time the binary is rebuilt and can be automated by adding the ''setcap'' target to your ''make'' command-line executed in ''src/sbbs3'':
