    ## Octopus Azure deployment script, version 1.0
    ## --------------------------------------------------------------------------------------
    ##
    ## This script is used to control how we deploy packages to Windows Azure.
    ##
    ## When the script is run, the correct Azure subscription will ALREADY be selected,
    ## and we'll have loaded the neccessary management certificates. The Azure PowerShell module
    ## will also be loaded.
    ##
    ## If you want to customize the Azure deployment process, simply copy this script into
    ## your NuGet package as DeployToAzure.ps1. Octopus will invoke it instead of the default
    ## script.
    ##
    ## The script will be passed the following parameters in addition to the normal Octopus
    ## variables passed to any PowerShell script.
    ##
    ## $OctopusAzureSubscriptionId // The subscription ID GUID
    ## $OctopusAzureSubscriptionName // The random name of the temporary Azure subscription record
    ## $OctopusAzureServiceName // The name of your cloud service
    ## $OctopusAzureStorageAccountName // The name of your storage account
    ## $OctopusAzureSlot // The name of the slot to deploy to (Staging or Production)
    ## $OctopusAzurePackageUri // URI to the .cspkg file in Azure Blob Storage to deploy
    ## $OctopusAzureConfigurationFile // The name of the Azure cloud service configuration file to use
    ## $OctopusAzureDeploymentLabel // The label to use for deployment
    ## $OctopusAzureSwapIfPossible // "True" if we should attempt to "swap" deployments rather than a new deployment
