# 
# Script to get source from SVN and build PrView
#
# Read the release notes to make ensure that the required software is installed.
#
# SVN must be installed:
# http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91
#
#
# On Windows:
#   - Make sure svn.exe in on the path. You might need to log out and log back in again after installing SVN.
#   - Inno Setup must be installed
#   - py2exe must be installed 
#   - mingw must be installed
#
# In Mac:
#   - py2app must be installed
#   - macholib must be installed to use py2app
#   - modulegraph must be installed to use py2app
#
# Usage:
# python build_prview [command]
# [command] can be any of the following:
#   -h: lists the command line options
#   -r: Builds a PrView using the released modules.
#   -t: Builds PrView from the trunk.
#   -i: Builds an installer from the release version.
#   -n: Print out the dependencies for the release notes
