 .B cfgfile   (Required Parameter - No Default)
 
-The the name of a file containing configuration information
+Declares where the configuration is found.  If this parameter is a
+.B string,
+it is treated as the name of a file to parse.  If this parameter
+is a
+.B list,
+\*(TC presumes this to be an in-memory configuration, and parses the
+list in sequential order, treating each entry as a configuration line.
+This allows you to use \*(TC for parsing either configuration files or
+in-memory configurations.  If you pass anything other than a string
+or list here, \*(TC will produce an error.
+
+.TP
+.B CallingProgram
+
+By default, each time \*(TC produces an Error, Warning, or Debug
+message, it prepends it with the string \'tconfpy\' followed by
+the version number.  Since \*(TC is designed to be called from
+applications programs, you may wish to substitute your own
+program name or other information in these messages.  You do so
+by setting the \fCCallingProgram\fp keyword to the desired text.
