# In fact, include/applet_tables.h depends only on applets/applet_tables,
# and is generated by it. But specifying only it can run
# applets/applet_tables twice, possibly in parallel.
# We say that it also needs NUM_APPLETS.h
#
# Unfortunately, we need to list the same command,
# and it can be executed twice (sequentially).
# The alternative is to not list any command,
# and then if include/applet_tables.h is deleted, it won't be rebuilt.
