+#!/bin/bash
+#
+# Usage:
+# process_plot_tasks nprocess time-range-ms
+#
+# Description:
+# Process all the thread info files in the current directory
+# creating task graphs for steps and threads.
+#
+# The input files are created by a run using the "-y interval" flag and
+# should be named "thread_info-step<n>.dat" in the current directory.
+# All located files will be processed using "nprocess" concurrent
+# processes and all plots will have the given time range. An output
+# HTML file "index.html" will be created to view all the plots.
