Notes:
  * You can specify multiple targets.
    ./build.sh <TARGET_1> <TARGET_2> <TARGET_N>
  * To get a list of all targets use \"help\". Hint: pipe the output through a pager.
    ./build.sh help | less
  * To build all targets use \"all\"
    ./build.sh all
  * To clean a target prefix it with \"clean_\".
    ./build.sh clean_MATEKF405SE
  * To clean all targets just use \"clean\".
    ./build.sh clean"
