+# webp scripts
+## lossless_z_gen_\* scripts
+Create images with various compression levels and see how that effects
+image size.  Has both a bash script to generate the images and an GNU
+octave script to generate the graph.
+## lossy_nearlossless_gen_\* scipts
+Much like the one but varies the nearlossless preprocessing level.  This
+just shows the file size but you need to look at the files because since
+it's lossy there will be visual compression artifacts.
+## Makefiles
+Just make files to convert directories of on going work PNGs to webps.
+There's a makefile for a single output and dual outputs for both a high
+and low quality compression settings.
