# Naming convention for Magic Lantern builds:
# General rules:
# - Always specify the camera and its firmware version number in the build name (e.g. 550d.fw109)
# - For non-release builds, specify the build date and author's (nick)name.
# - For experimental builds, add a short keyword indicating the particular feature tested.

# Examples for experimental builds:
# magiclantern-2010dec07.550d.fw108.cropmarks.a1ex.zip 
# magiclantern-2010nov23.550d.fw108.selectable-audio.piers.zip 

# Example for pre-release builds:
# magiclantern-2010dec17.550d.fw109.PRERELEASE.alex.zip

# Release builds:
# magiclantern-0.2.0.rc1.550d.fw109.zip
#~ VERSION=0.2.0.rc1.550d.fw109
