 * it with the build subcommand. This is because we want run `build-chain build resume` as it is more 
 * intuitive than `build-chain build resume`. However internally we still need it to act as a tool because
 * it doesn't follow the usual build process. Hence we set resume as a tools command as part of the parsed inputs
 * internally.
