+The purpose of this file is to collect some handy functions. The reason they
+are not in PathUtils (and there is this confusing naming going on) is that
+PathUtils depends on PathJob. Which makes it impossible to use the functions
+and classes defined there in PathJob.
+
+So if you add to this file and think about importing anything from PathScripts
+other than PathLog, then it probably doesn't belong here.
