#
# This file provides common Makefile infrastructure for several Prometheus
# components. This includes make tasks for downloading Go, setting up a
# self-contained build environment, fetching Go dependencies, building
# binaries, running tests, and doing release management. This file is intended
# to be included from a project's Makefile, which needs to define the following
# variables, at a minimum:
#
# * VERSION - The current version of the project in question.
# * TARGET - The desired name of the built binary.
#
# Many of the variables defined below are defined conditionally (using '?'),
# which allows the project's main Makefile to override any of these settings, if
# needed. See also:
#
# https://www.gnu.org/software/make/manual/html_node/Flavors.html#Flavors.
#
# The including Makefile may define any number of extra targets that are
# specific to that project.
