DELETE=0

function usage {
cat <<EOT
Usage:
        $NAME [-l <number>] [-n MY_NAME][-a] [-d] [-h]
Purpose:
        In Azure, build the labs for the NGINXaaS workshop. 
        - Must have valid NGINX Plus JWT in Lab 3 folder.
        - Azure CLI must be installed and logged in.
        - Currently tested on OS X

Inputs:
      -l NUMBER
            This option allows you to choose which lab to build. Labs are built 
            on top of each other (there are dependencies), so prior labs will be 
            built.
      -a
            Build lab2, 3 or 4. All labs should be built sequentially.
      -d
            Delete the whole resource group (will ask for confirmation)
      -h
            Display this usage help text
      -t
            Test basic environment setup to be sure the script can run.
