# A Makefile to be (optionally) included by any SDK applications.
#
# This Makefile assumes the following environment variables:
#   ROOT
#   	Points to the root of the Hue installation. From here, we
#   	can include $(ROOT)/Makefile.vars to access various variables.
#
# This Makefile (or any custom application Makefile) MUST provide the following
# targets:
#   egg-info
#   	Responsible for creating the egg-info directory for the application.
#
#   ext-eggs
#   	Responsible for creating a Python egg for each external Python
#   	dependency. These eggs should be placed in the
#   	$(APP_ROOT)/ext-py/<package>/dist directory.
#
#   clean
#   	Remove build products.
#
#   sdist
#   	Responsible for making a source distribution directory at
#   	$(APP_ROOT)/build/sdist/$(APP_NAME).
#
#   install-bdist
#   	Responsible for installing a built distribution to a target directory,
#   	as specified by $(INSTALL_DIR).
