# NeuralSPOT is structured to ease adding modules
# Adding a module is as simple as creating a directory,
# populating it with a modules.mk, and adding it to the
# 'modules' list below.

# There are certain hardcoded assumptions that must be followed
# When adding a module. Module directories must look something like this:
# .../mymodule/
#   module.mk
#   src/ <- contains C, CC, S, and private H files
#   includes-api/ <- contains public header files
#
# Build artifacts (.o, .d, etc) are placed
# in the $BINDIR directory (defaults to 'build') which is
# created when needed and remove by 'make clean'
#
# The module.mk contents differ slightly depending on
# the type of module (example, extern, or library), but
# generally work by adding values to a set of variables
# (see below). When adding a new module, it is best
# to copy an existing module.mk and modifying it.
