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.
