# This is used to install a bunch of resource files somewhere.  It is
# different from a bundle without resources; in a bundle without
# resources, we first create the bundle in the build directory, then
# copy the build to the install dir, overwriting anything already
# there.  This instead will install the separate resource files
# directly in the installation directory; it's more efficient as it
# doesn't create a local bundle, and it doesn't overwrite an existing
# bundle in the installation directory.
#
#
# The name of the set of resources is in the RESOURCE_SET_NAME variable.
# The list of resource files/dirs is in xxx_RESOURCE_FILES
# The list of resource directories to create are in xxx_RESOURCE_DIRS
# The directory in which to install the resources is in the
#                xxx_INSTALL_DIR
# The directory in which the resources are is in the 
#                xxx_RESOURCE_FILES_DIR (defaults to ./ if omitted)
# The list of LANGUAGES is in the xxx_LANGUAGES variable.
# The list of localized files/dirs to be read from yyy.lproj and copied
#    into $(RESOURCE_FILES_INSTALL_DIR)/yyy.lproj for each language yyy
#    is in the xxx_LOCALIZED_RESOURCE_FILES variable.
# The list of localized dirs to be created empty inside each
#    $(RESOURCE_FILES_INSTALL_DIR)/yyy.lproj for each language yyy
#    is in the xxx_LOCALIZED_RESOURCE_DIRS variable.
