+The following scripts can make useful plots (some use the
+`detonation.py` module as support):
 
+* `det_speed_comp.py` : plot detonation speed vs. resolution, using
+  simple differencing to estimate the detonation speed from the last 3
+  plotfiles.
+
+* `profile_compare.py` : given a list of pruns (from different
+  resolutions), make a plot showing all of their profiles together.
+
+* `profiles.py` : for a single run, plot profiles of T and enuc for
+  several times.
+
+* `show_shock_flag.py` : simply plot the shock variable on top of T
+  and enuc profiles.
+
+* `zoom_summary.py` : given a list of runs (from different
+  resolutions), plot the last plotfile from each run, zoomed in on
+  where the peak energy generation is.
