+JPEG XL image coding system is particularly optimised for
+responsive web environments so that content renders well on
+a wide range of devices.Existing JPEG files can be losslessly
+transcoded to JPEG XL and can also restored to exact same JPEG
+file ensuring backward compatibility.
+
+JPEG XL is designed to meet the needs of image delivery on the 
+web and professional photography. It supports wide colour gamut 
+as well as high dynamic range and high bit depth images. JPEG XL 
+further includes features such as animation, alpha channels, layers, 
+thumbnails, lossless and progressive coding to support a wide range 
+of use cases including but not limited to photo galleries, e-commerce, 
+social media, user interfaces and cloud storage. To enable novel 
+applications, it also adds support for 360 degree images, 
+image bursts, large panoramas/mosaics, and printing.

+# 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 ':' except on otherwise blank lines.
