Setting -e option in a shell script causes the shell to exit
immediately if a command exits with a non-zero status.

So you can write many commands without && and \s.

  set -e
  echo "Building ${VERSION}-${SUFFIX}"
  mkdir ${VERSION}-${SUFFIX}
  cd ${VERSION}-${SUFFIX}
  ../configure --prefix=/usr/local --program-suffix=19
  make
  sudo make install

A difference is that it exits with a non-zero status by -e.
