+#
+# Usage: gr2ps [options] <gr-file>
+#
+# Transform the log file of a GrAnSim run (a .gr file) into a quasi-parallel
+# profile (a .qp file) and then into a PostScript file, showing essentially
+# the total number of running, runnable and blocked tasks.
+#
+# Options:
+#  -o <file> ... write PS file to <file>
+#  -i <int>  ... info level from 1 to 7; number of queues to display
+#  -m        ... create mono PostScript file instead a color one.
+#  -O        ... optimize the produced .ps w.r.t. size
+#		 NB: With this option info is lost. If there are several values
+#		     with same x value only the first one is printed, all 
+#		     others are dropped.
+#  -s <str>  ... print <str> in the top right corner of the generated graph
+#  -v        ... be talkative. 
+#  -h        ... print help message (this header).
