| 21 | +# This file provides common Makefile infrastructure for several Prometheus |
| 22 | +# components. This includes make tasks for downloading Go, setting up a |
| 23 | +# self-contained build environment, fetching Go dependencies, building |
| 24 | +# binaries, running tests, and doing release management. This file is intended |
| 25 | +# to be included from a project's Makefile, which needs to define the following |
| 26 | +# variables, at a minimum: |
| 27 | +# |
| 28 | +# * VERSION - The current version of the project in question. |
| 29 | +# * TARGET - The desired name of the built binary. |
| 30 | +# |
| 31 | +# Many of the variables defined below are defined conditionally (using '?'), |
| 32 | +# which allows the project's main Makefile to override any of these settings, if |
| 33 | +# needed. See also: |
| 34 | +# |
| 35 | +# https://www.gnu.org/software/make/manual/html_node/Flavors.html#Flavors. |
| 36 | +# |
| 37 | +# The including Makefile may define any number of extra targets that are |
| 38 | +# specific to that project. |
