+# Convert an RMM text variable into an actual Boolean value.
+Function ConvertTo-RmmBoolean {
+    <#
+    .SYNOPSIS
+    Converts an RMM text value to a System.Boolean.
+    .DESCRIPTION
+    Accepts true, $true, yes, y, or 1; false, $false, no, n, or 0.
+    Matching ignores case and surrounding whitespace. Null and empty values
+    return false. Unrecognized values throw instead of silently enabling an option.
+    .PARAMETER Value
+    The value to convert. Native Boolean values are also accepted.
+    .PARAMETER VariableName
+    Optional RMM variable name, without the leading $, for error messages.
+    .EXAMPLE
+    $ZipEnabled = ConvertTo-RmmBoolean -Value $Zip -VariableName 'Zip'
+    .EXAMPLE
+    ConvertTo-RmmBoolean ' No '
