# Glimmer provides a JRuby Desktop UI DSL + Data-Binding functionality
#
# A desktop UI application class must include Glimmer to gain access to Glimmer DSL
#
# Glimmer DSL static keywords (e.g. rgb, bind, etc..) are available as inherited methods
# Glimmer DSL dynamic keywords (e.g. label, combo, etc...) are available via method_missing
