+"""
+This package implements some extensions to the standard Python logging module that
+support a consistent logging and bug reporting framework for Gramps.
+
+The package provides:
+
+  GtkHandler - a log handler that will pop up a gtk dialog when a log message is
+               sent to it. The dialog offers the user the chance to start
+               ErrorReportAssistant to send a bug report.
+
+  RotateHandler - a log handler that just keeps a rotating buffer of the last N
+               log messages sent to it. This can be used with the GtkHandler to
+               pass a history of log messages to the ErrorReportAssistant.
+
+Usage:
+
+   These handlers can be used in same way a all the other logger module handlers.
+
+   Simple example:
+
+        from GrampsLogger import GtkHandler, RotateHandler
+
+        rh = RotateHandler(capacity=20)
+        rh.setLevel(logging.DEBUG)
+        
+        gtkh = GtkHandler(rotate_handler=rh)
+        gtkh.setLevel(logging.ERROR)
+
+        l = logging.getLogger("GtkHandlerTest")        
+        l.setLevel(logging.DEBUG)
+
+        l.addHandler(rh)
+        l.addHandler(gtkh)
+
+        log_message = "Debug message"
+        try:
+            wibble
+        except:
+            l.error(log_message,exc_info=True)
+
+        gtk.main()
