        A wrapper build tool
        
        Motivation
        ==========
        
        When writing something such as a build tool, there is always the question:
        "why?". Why write yet another build tool?
        
        Well, there are several reasons that are the backing motivation:
        
        First, developing a variety of software, using one and only one build tool for
        every project is nearly (if not entirely) impossible. There is a desire to have
        a consistent build step and process when testing and deploying. Given the
        environment in which the code is written is heterogeneous, having one uniform
        build tool that wraps itself around the other ones (and has the ability to
        expand to new ones) is ideal.
        
        Second, short of dropping into the language the build tool was written in,
        expanding some build steps is very difficult (or at least can be). Further
        there can be complicated build targets that require some interesting and
        potentially involved (smelly) procedures to be accomplished, that may or may
        not be easy to describe in the build file or in the native language. Therefore,
        having a wrapping build framework/ tool that is written in an easy to read and
        write language, such as Python, these complicated steps can depend less on some
        funky new build library (further adding to the dependency tree) and can become
        just implementation details. [awkward?]
        
        Last, and most certainly the least, I wanted to explore the idea. I wanted to
        write something that made me think about solving some of the problems
        challenged by such a tool.
        
        What Xnt Is NOT
        ===============
        
        Calling Xnt simply a build tool is (grossly?) misleading. Xnt is not really a
        build tool in the traditional sense. Like stated above, it is more a wrapper
        around existing build tools. I didn't want to replace what some of these tools
        already do really well (e.g. being able to describe how to compile an entire
        large Java program in several lines of code using Ant).
        
        What Xnt IS
        ===========
        
        Xnt is a wrapping build tool, intended to be used with a multitude of sub-build
        tools, even in the same project. Regardless of the language the project is
        written in, Xnt should be able to suite your needs. If your language's build
        tool is unable to do something concisely or cleanly, Python should help. [There
        could be more here... I can't think of it though.]
        
        Installing and Setting Up Xnt
        =============================
        
        Using Xnt is fairly simple. All you will need to do is install it, create a
        ``build.py`` file for your project, and invoke it just like any other build
        tool you have used before (e.g. ``$ xnt {target}``).
        
        Dependencies
        ------------
        
        Xnt has a few dependencies, specifically, Mercurial (for ``Hg`` use), CVS (for
        ``cvs`` use), ``NAnt``, ``Ant``, ``Make``, and ``distribute``. Currently, the
        dependencies are just assumed to be there, so you may, if you want, ignore
        them. However, you may not be able to easily install Xnt without
        ``distribute``.
        
        Source Install
        --------------
        
        To install from source, you can download the source tarball or zip file, unpack
        it into a temporary directory and then, from a shell or command prompt, run
        ``$python[2] setup.py install [--user]``.
        
        PyPi/ Pip
        ---------
        
        Soon I will attempt to get this package up to `PyPi
        <http://pypi.python.org/pypi>`_.
        
        Linux/ Unix
        -----------
        
        After installing under Gnu/Linux or Unix, you are set. There is nothing more
        you will need to do.
        
        Windows
        -------
        
        If on Windows, after installing you will need edit your ``PATH`` environment
        variable to include the ``<python_install_dir>\Scripts`` folder. After which,
        you will be all set to use Xnt.
        
        Example ``build.py``
        ====================
        
        Here is a simple ``build.py``::
        
            #!/usr/bin/env python
        
            from xnt import target
            from xnt.tasks import *
            from xnt.builders import ant
        
            @target
            def init():
                mkdir("bin")
        
            @target
            def build():
                init()
                ant("build")
        
            @target
            def clean():
                rm("bin")
        
            @target
            def rebuild():
                clean()
                build()
        
            @target
            def package():
                rebuild()
                zip("bin", "packaged.zip")
        
            @target
            def default():
                package()
        
        As you can see, it really just is a Python script. There really isn't anything
        really special happening. We just import some of the Xnt modules, and define
        some targets. When you call ``xnt``, it will be loading this script and call
        the target specified by ``{target}`` or, if you don't specify one, it will call
        the target named ``default``.
