<#
.SYNOPSIS
    Builds a Bicep file to ARM, following best practices presented in:
    https://github.com/Azure/azure-quickstart-templates/blob/master/1-CONTRIBUTION-GUIDE/README.md.

.PARAMETER CopyOutputToClipboard
    Copy the ARM JSON output to the clipboard.
#>

# PowerShell 5's `ConvertTo-Json` has suboptimal JSON formatting
# and will cause diffs just on whitespace with other contributors
# to the repository, so we enforce V7 or higher.
#Requires -Version 7.0
