# Top-level Makefile for Gitaly
#
# Responsibilities of this file:
# - create GOPATH in _build with symlink to current dir
# - re-generate _build/Makefile from makegen.go on each run
# - dispatch commands to _build/Makefile
#
# Besides the targets that manage _build and _build/Makefile, all
# targets in this Makefile should look like this:
#
# .PHONY: foobar
# foobar: prepare-build
# 	cd $(BUILD_DIR) && $(MAKE) $@
#
# All other logic should happen in _support/Makefile.template and
# _support/makegen.go.
#
