47+### Makefile Support

48+

49+This buildpack now supports an optional Makefile, in case you need to coordinate

50+other build steps with Stack. It assumes that the Makefile includes a `make

51+install` target that uses the Stack build command with the flag `--copy-bins`.

52+For example, a possible `install` target configuration in the Makefile could be:

53+

54+ install:

55+ stack build --copy-bins
