various kludges legacy packages are using to install data in their package
directories.  Some use absolute paths in 'distribution.data_files', while
others create various subclasses of 'install_data', each with their own
way of finding out what directory to use!  So 'bdist_egg' now does all its
'install_lib' activity before 'install_data', and pokes the desired build
directory into a wide variety of places, so that all of the known kludges
so far will work correctly.  It also checks for absolute paths in
'data_files' (carefully working around other packages' 'data_files'
kludges!) and converts them back to relative ones, if they are subpaths of
site-packages.

Clearly, we need to get the word out about 'package_files' in Python 2.4
and above, and suggest using 'setuptools' for Python 2.3.

EasyInstall now recognizes both 'svn' URLs (including 'svn+ssh' et al), and
notices when it connects to an HTTP server that's actually a subversion

and builds and installs them as eggs, with support for managing .pth files.
Built distributions are installed in individual subdirectories, so you can
either add the directory to a .pth (automatically done by default), or you
can use pkg_resources.require() to manage your dependencies explicitly.
Because each distribution is in its own directory (or .egg file),
uninstallation and clean upgrades are trivial, without the aid of any sort
of package manager.

distutils custom command hack in the field is to make 'install_data'

initially and fixing them up when new eggs are added to sys.path.  At the
moment, all namespace packages are fixed up whenever any new egg is added
to sys.path, but this might not scale well if there are lots of eggs and
lots of namespace packages.  Perhaps we should limit namespace fixups to
namespace packages explicitly declared in the egg?

be refactored later to support registering adapters for arbitrary PEP 302
