 ===== Log Messages =====
+ACT supports debug log messages in verbose mode. A debug log statement can be written as:
+<code act>
+...
+${ "Hello!" };   // log message "Hello"
+...
+</code>
+When this construct is encountered, a log message is displayed. By default these messages are ignored; to see them, use the ''-Vconfig'' ACT command-line option to any ACT tool. (Note that this will also display the names of the configuration files loaded by ACT.)
+A log message can include multiple values,  including parameter expressions. This can be useful to check values of parameters.
+<code act>
+${ "Parameter i has value ", i };  // display the value of i
+</code>
