  -D          Run make dist in addition to "all install"
  -d          Run make distcheck in addition "all install"
  -g          Compile and link with debug information
  -h, --help  Display this help and exit successfully
  -n          Do not quit after error; just print error message
  -o <module/component> Build just this <module/component>
  -p          Update source code before building (git pull --rebase)
  -s <sudo>   The command name providing superuser privilege
  --autoresume <file> Append module being built to, and autoresume from, <file>
  --check     Run make check in addition "all install"
  --clone     Clone non-existing repositories (uses $GITROOT if set)
  --cmd <cmd> Execute arbitrary git, gmake, or make command <cmd>
  --modfile <file> Only process the module/components specified in <file>

Usage: build.sh -L
  -L          List the components to build to stdout
