# Allows a pre-built image to be used (if it exists) for installing
# Whonix.  This option is useful only for debugging Whonix installations
#
# To use, first create a regualr wheezy template and manually copy the prepared 
# image to debian-7-x64-prepard.img
#
# Example:
# cp ~/qubes-builder/qubes-src/linux-template-builder/prepared_images/debian-7-x64.img ~/qubes-builder/qubes-src/linux-template-builder/prepared_images/debian-7-x64-whonix-gateway-prepard.img
