Windows Build Script
--------------------

This script is used to build the Windows binary and the accompanying installer.
For this script to work out of the box, it depends on a number of things:

Python 2.6
    This build script only works with Python 2.6.

PyQt4
    You should already have this installed, OpenLP doesn't work without it. The
    version the script expects is the packaged one available from River Bank
    Computing.

PyEnchant
    This script expects the precompiled, installable version of PyEnchant to be
    installed. You can find this on the PyEnchant site.

Inno Setup 5
    Inno Setup should be installed into "C:\%PROGRAMFILES%\Inno Setup 5"

UPX
    This is used to compress DLLs and EXEs so that they take up less space, but
    still function exactly the same. To install UPS, download it from
    http://upx.sourceforge.net/, extract it into C:\%PROGRAMFILES%\UPX, and then
    add that directory to your PATH environment variable.

PyInstaller
    PyInstaller should be a checkout of revision 844 of trunk, and in a
    directory called, "pyinstaller" on the same level as OpenLP's Bazaar shared
    repository directory. The revision is very important as there is currently
    a major regression in HEAD.

    To install PyInstaller, first checkout trunk from Subversion. The easiest
    way is to install TortoiseSVN and then checkout the following URL to a
    directory called "pyinstaller"::

        http://svn.pyinstaller.org/trunk

    Then you need to copy the two hook-*.py files from the "pyinstaller"
    subdirectory in OpenLP's "resources" directory into PyInstaller's "hooks"
    directory.

    Once you've done that, open a command prompt (DOS shell), navigate to the
    PyInstaller directory and run::

        C:\Projects\pyinstaller>python Configure.py

Bazaar
    You need the command line "bzr" client installed.

OpenLP
    A checkout of the latest code, in a branch directory, which is in a Bazaar
    shared repository directory. This means your code should be in a directory
    structure like this: "openlp\branch-name".

windows-builder.py
    This script, of course. It should be in the "scripts" directory of OpenLP.
