+Pillow is a replacement for PIL that works as a drop-in replacement.
+Unlike PIL, it's actively maintained and easy to install. It's pretty great.
+There's only one problem, which is that users must first uninstall PIL before
+installing Pillow, as they share a namespace.
+
+This makes it very hard for Python modules or products that need to run on a
+variety of configurations to easily depend on either PIL or Pillow without
+inevitably breaking something (perhaps in subtle ways). That makes it hard to
+safely transition.
+
+This package aims to "solve" that by providing a single dependency that can
+intelligently depend on either PIL or Pillow, based on what's already on the
+system. Packages that still need to work if PIL is installed, but aim to
+transition to Pillow, can simply depend on the pillowfight package.
