       0  Just run pngcrush. It removes unnecessary chunks and perform basic
          optimization on the encoded data.
       1  Optimize png files using pngout/optipng and advdef. This can further
          reduce addtional 5~30%. This is the default level.
       2  Aggressively optimize the size of png files. This may produce
          addtional 1%~5% reduction.  Warning: this is *VERY*
          slow and can take hours to process all files.
   -r<revision> If this is specified, the script processes only png files
                changed since this revision. The <dir> options will be used
                to narrow down the files under specific directories.
+  -c<commit>   Same as -r but referencing a git commit. Only files changed
+               between this commit and HEAD will be processed.
   -v  Shows optimization process for each file.
   -h  Print this help text."
