+# @brief Common functions and variables for Tool Under Test (TUT).
+#
+# The script requires variables:
+# TUT_PATH - Assumed absolute path to the directory in which the TUT is located.
+# TUT_NAME - TUT name (without path).
+#
+# The script sets the variables:
+# TUT - The path (including the name) of the executable TUT.
+# error_prompt - Delimiter on error.
+# error_head - Header on error.
+
+# Complete the path for Tool Under Test (TUT). For example, on Windows, TUT can be located in the Debug or Release
+# subdirectory. Note that Release build takes precedence over Debug.
