"""
This script is used to build "official" universal installers on Mac OS X.
It requires at least Mac OS X 10.5, Xcode 3, and the 10.4u SDK for
32-bit builds. 64-bit or four-way universal builds require at least
OS X 10.5 and the 10.5 SDK.
Please ensure that this script keeps working with Python 2.5, to avoid
bootstrap issues (/usr/bin/python is Python 2.5 on OSX 10.5). Sphinx,
which is used to build the documentation, currently requires at least
Python 2.4.
In addition to what is supplied with OS X 10.5+ and Xcode 3+, the script
requires an installed version of hg and a third-party version of
Tcl/Tk 8.4 (for OS X 10.4 and 10.5 deployment targets) or Tcl/TK 8.5
(for 10.6 or later) installed in /Library/Frameworks. When installed,
the Python built by this script will attempt to dynamically link first to
Tcl and Tk frameworks in /Library/Frameworks if available otherwise fall
back to the ones in /System/Library/Framework. For the build, we recommend
installing the most recent ActiveTcl 8.4 or 8.5 version.
32-bit-only installer builds are still possible on OS X 10.4 with Xcode 2.5
and the installation of additional components, such as a newer Python
(2.5 is needed for Python parser updates), hg, and svn (for the documentation
build).
Usage: see USAGE variable in the script.
