"""
Mac OS X Build Script
--------------------

This script is used to build the Mac OS X app bundle and pack it into dmg file.
For this script to work out of the box, it depends on a number of things:

Python 3.3/3.4

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.

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

PyInstaller
    PyInstaller should be a git clone of either
    https://github.com/matysek/pyinstaller branch python3 or
    https://github.com/pyinstaller/pyinstaller branch python3

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".

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

Mako
    Mako Templates for Python.  This package is required for building the
    remote plugin.

Alembic
    Required for upgrading the databases used in OpenLP.

MuPDF
    Required for PDF support in OpenLP. Install using macports, or use the
    mudrawbin option in the config file to point to the mudraw binary.

MachOLib
    Python library to analyze and edit Mach-O headers, the executable format
    used by Mac OS X. Used to relink the mudraw binary from MuPDF to the bundled
    libraries. Install using macports or pip.

config.ini.default
    The configuration file contains settings of the version string to include
    in the bundle as well as directory and file settings for different
    purposes (e.g. PyInstaller location or installer background image)

To install everything you need to install MacPorts. Once MacPorts is installed
and up-to-date, run the following command::

    $ sudo port install python34 py34-pyqt4 py34-sphinx py34-sqlalchemy \
                        py34-macholib py34-mako py34-alembic py34-enchant \
                        py34-beautifulsoup4 py34-lxml py34-nose

You may need to install chardet via pip::

    $ sudo pip install chardet
