# Since rjb imports Java classes without creating a corresponding

# monkey patch any class, so additional methods must be added
# to each Screen object.
#
# All Java classes' methods are immediately available in the proxied
# Ruby classes, but care has to be given to match their type. For a
# list of methods, see: <http://doc.sikuli.org/javadoc/index.html>.
# The type "PRSML" is a union of Pattern, Region, Screen, Match and
# Location.

#     def Sikuli::Screen.new
# so we work around it with the following vairable.
