Dependencies
============

Note that these dependencies should automatically be satisfied by the
installation procedure and do not need to be acquired separately.

setuptools:
   `setuptools`_ provides enhancements to `distutils`_.

macholib:
    `macholib`_ reads and writes the Mach-O object file format.
    Used by py2app to build a dependency graph of dyld and framework
    dependencies for your application, and then to copy them into your
    application and rewrite their load commands to be ``@executable_path``
    relative. The end result is that your application is going to be
    completely standalone beyond a default install of Mac OS X. You no
    longer have to worry about linking all of your dependencies statically,
    using `install_name_tool`_, etc. It's all taken care of!

modulegraph:
    `modulegraph`_ is a replacement for the Python standard library
    `modulefinder`_. Stores the module dependency tree in a graph data
    structure and allows for advanced filtering and analysis capabilities,
    such as `GraphViz`_ dot output.

altgraph:
    `altgraph`_ is a fork of `Istvan Albert`_'s graphlib, and it used
    internally by both `macholib`_ and `modulegraph`_. It contains
    several small feature and performance enhancements over the original
    graphlib.
