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 3.4

PyQt5
    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"

Sphinx
    This is used to build the documentation.  The documentation trunk must be at
    the same directory level as OpenLP trunk and named "documentation".

HTML Help Workshop
    This is used to create the help file.

PyInstaller
    PyInstaller should be a git clone of
    https://github.com/matysek/pyinstaller branch develop

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".

Visual C++ 2008 Express Edition
    This is to build pptviewlib.dll, the library for controlling the
    PowerPointViewer.

windows-builder.py
    This script, of course. It should be in the "windows-installer" directory
    at the same level as OpenLP trunk.

psvince.dll
    This dll is used during the actual install of OpenLP to check if OpenLP is
    running on the users machine prior to the setup.  If OpenLP is running,
    the install will fail.  The dll can be obtained from here:

        http://www.vincenzo.net/isxkb/index.php?title=PSVince

    The dll is presently included with this script.

Mako
    Mako Templates for Python.  This package is required for building the
    remote plugin.  It can be installed by going to your
    python_directory\\scripts\\.. and running "easy_install Mako".  If you do not
    have easy_install, the Mako package can be obtained here:

        http://www.makotemplates.org/download.html

MuPDF
    Required for PDF support in OpenLP. Download the windows build from
    mupdf.com, extract it, and set the mutoolbin option in the config file to
    point to mutool.exe.

MediaInfo
    Required for the media plugin. Download the 32-bit CLI windows build from
    https://mediaarea.net/nn/MediaInfo/Download/Windows and set the
    mediainfobin option in the config file to point to MediaInfo.exe.

Portable App Builds
    The following are required if you are planning to make a portable build of
    OpenLP.  The portable build conforms to the standards published by
    PortableApps.com:

        http://portableapps.com/development/portableapps.com_format

    PortableApps.com Installer:

        http://portableapps.com/apps/development/portableapps.com_installer

    PortableApps.com Launcher:

        http://portableapps.com/apps/development/portableapps.com_launcher

    NSIS Portable (Unicode version):

        http://portableapps.com/apps/development/nsis_portable
