+/**
+ * \file test-installer-lib-sandbox.cpp
+ *
+ * Automatic testing of many of the units within the custom action is infeasible.
+ * In one case, they rely on the execution environment within an installation session.
+ * In another, they rely on the operation system environment as a whole.
+ * In these cases, it's easier to verify behavior manually.
+ *
+ * This file contains a custom action function sandbox() as well as a number of test functions.
+ * At any given time, not all of the test functions need to be referenced within the body of custom action.
