+
+Animate a 1D plot of FDS in-depth profile (CHID_prof_n.csv)
+
+Usage: Copy this script to your working directory and add your
+       profiles to the filenames list.
+
+       Use option --with_slider to control the animation with a time slider
+       Use option --save_animation to save the animation (no slider) to a movie file
+
+Example:
+
+$ python prof1d.py --with_slider
