# A Makefile for assembling and linking the code snippets. By default,
# the rules generate outputs in build-bin/sw/otbn/build-subdir.
#
# This is a thin wrapper around ./rules.mk. To customise exactly what
# gets built where, include rules.mk in your own Makefile (see
# documentation there) and set the otbn-code-snippets-* variables
# appropriately.
