+#
+# Usage: tf [options] <gr-file>
+#
+# Show the `taskflow' in the .gr file (especially useful for keeping track of 
+# migrated tasks. It's also possible to focus on a given PE or on a given
+# event.  
+# 
+# Options:
+#  -p <int> ... Print all events on PE <int>
+#  -t <int> ... Print all events that occur on task <int>
+#  -e <str> ... Print all <str> events
+#  -n <hex> ... Print all events about fetching the node at address <hex>.
+#  -s <int> ... Print all events with a spark name <int>
+#  -L       ... Print all events with spark queue length information
+#  -H       ... Print header of the <gr-file>, too
+#  -h       ... print help message (this text)
+#  -v       ... be talkative
