-"""Package Install Manager for Python.
-
-This is currently a MacOSX-only strawman implementation.
-Despite other rumours the name stands for "Packman IMPlementation".
-
-Tools to allow easy installation of packages. The idea is that there is
-an online XML database per (platform, python-version) containing packages
-known to work with that combination. This module contains tools for getting
-and parsing the database, testing whether packages are installed, computing
-dependencies and installing packages.
-
-There is a minimal main program that works as a command line tool, but the
-intention is that the end user will use this through a GUI.
