#   GHCFLAGS = -O2 -dynamic
#   GHC = ghc-7.6

# GHC Parameters
GHCIMPORTDIRS ?=
GHCFLAGS ?=
GHC ?= ghc

# Makefile where to keep the dependencies
DEPMK ?= mk/depend.mk

# By default, excludes dist and Setup.hs, so that a Makefile can coexist nicely
# in a cabalized project.  Also excludes .stack-work.

# It should include all Haskell sources to be compiled by different targets
# (even those that are not a dependency to all)
# It will be used to generate dependencies and for cleaning objects
