# This Makefile essentially lists the applications, and delegates build targets
# through to them.
#
# The interesting bit is done by the recursive_app_make_target macro (see below).
# In essence, the important targets are:
#
#   install-binary-apps
#      installs built applications into the install dir, without
#      installing them into a virtual environment.
#
#   env-install
#      installs all of the applications into the virtual environment
#
#   clean
#      cleans up
#
