# This makefile offers high-performance (cached) wrappers that enrich the classpath, for optimal IDE functioning.
# We suggest that you copy/merge this file into your project.
# We believe it's best to give you something that you can freely understand and hack locally.
# The tradeoff is that you may have to catch up with important fixes/improvements to this Makefile, if any.
# Feel free to suggest any improvements at:
# https://github.com/clojure-emacs/enrich-classpath/issues

# Allows you to simply type `make`, the default task will be run for you.
# Feel free to choose one of: lein-repl | deps-repl
