      Pharo's goal is to deliver a clean, innovative, free open-source
      Smalltalk-inspired environment. By providing a stable and small core
      system, excellent dev tools, and maintained releases, Pharo is an
      attractive platform to build and deploy mission critical applications.

      This package provides the executable VM. You should probably not care
      about this package (which represents a packaging detail) and have a
      look at the pharo-vm-core package instead.

      Please fill bug reports on http://bugs.pharo.org under the 'Ubuntu
      packaging (ppa:pharo/stable)' project.
