# Export template - a simple script showing boiler plate for an export script
#
# Put this script in the [addons] folder. Under OS-X, you need to right click
# on the blender executable and select 'show package content' to access scripts
# (blender/Contents/MacOS/scripts/addons)
#
# IMPORTANT: to enable a script, go to [user preferences] and select the add-ons tab.
# Find the script and check/uncheck the box on the right to enable/disable.
# If you can't check the box to enable, likely there is a syntax error.
# Enable/disable is also convenient while testing, you can uncheck-check to reload
# the script.
