"""Python script to build the OSX universal binaries.
This is a simple script, most of the heavy lifting is done in bdist_mpkg.
To run this script: 'python build.py'
Requires a svn version of scipy is installed, svn is used to revert
file changes made to the docs for the end-user install. Installer is
built using sudo so file permissions are correct when installed on
user system. Script will prompt for sudo pwd.
