# This script retrieves all the dependencies required and cross-compiles
# pyexiv2 for windows on a linux host.
#
# Typical dependencies (of this script) on an Ubuntu system:
#  wget unzip tar build-essential mingw32 p7zip-full bjam
#
# After execution is complete, copy the following file and folder to the
# site-packages directory of a Python 2.6 windows setup:
#  - $BASE/pyexiv2/build/libexiv2python.pyd
#  - $BASE/pyexiv2/src/pyexiv2
