# This script builds a binary install package of OpenSCAD for Windows
# using a cross-built mingw OpenSCAD and the NSIS installer system
#
# This script must be run from the OpenSCAD source root directory
#
# Usage: ./scripts/mingw-x-build-installer.sh
#
# Result: binary installer in $DEPLOYDIR directory
#
#
# Prerequisites:
#
#   source ./scripts/setenv-mingw-xbuild.sh
#   ./scripts/mingw-x-build-dependencues.sh
#
# and then build openscad before running this script.
#
# You need MCAD. run 'git submodule init && git submodule update'
#
# You need the Nullsoft installer system, on ubuntu 'sudo apt-get install nsis'
#
# Also see http://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Cross-compiling_for_Windows_on_Linux_or_Mac_OS_X
