# We are using _make magic_ for turning these file-targets into calls to
#  sub-Makefiles in the individual modules.
# These sub-Makefiles need to be kept in sync with the template, hence we
#  add a dependency on each modules Makefile and cross-link that to the
#  template at the very top of this file.
# Example: `web$ make modules/server-ce-scripts/test_acceptance_server_ce`
# Description: Run the acceptance tests of the server-ce-scripts module in a
#               Server CE Environment.
# Break down:
#  Target: modules/server-ce-scripts/test_acceptance_server_ce
#    -> depends on modules/server-ce-scripts/Makefile
#    -> add environment variable BASE_CONFIG=$(CFG_SERVER_CE)
#    -> BASE_CONFIG=/app/test/acceptance/config/settings.test.server-ce.js
#    -> automatic target: `make -C server-ce-scripts test_acceptance_server_ce`
#    -> automatic target: run `make test_acceptance_server_ce` in module
#  Target: modules/server-ce-scripts/Makefile
#    -> depends on Makefile.module
#    -> automatic target: copies the file when changed
