+WebP is a method of lossy compression that can be used on photographic
+images. The degree of compression is adjustable so a user can choose
+the trade-off between file size and image quality.
+WebP typically achieves an average of 39% more compression than JPEG 
+and JPEG 2000, without loss of image quality.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
