+<#  
+.SYNOPSIS  
+    Distribute the tests in VSTS pipeline across multiple agents 
+.DESCRIPTION  
+    This script divides test files across multiple agents for running on Azure DevOps.
+    It is adapted from the script in this repository: 
+    https://github.com/PBoraMSFT/ParallelTestingSample-Python/blob/master/DistributeTests.ps1
+
+    The distribution is basically identical to the way we do it in .travis.yaml
