From: Arnout Vandecappelle (Essensium/Mind) Date: Tue, 12 Mar 2019 17:55:35 +0000 (+0100) Subject: docs/manual: document new behaviour of 'make printvars' X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=71d0cddeacc1c626780c9e47345a322b39eaf0c7;p=buildroot.git docs/manual: document new behaviour of 'make printvars' Add a 'VARS=...' setting to the example. To make it clear that several variables can be specified, use two variables in the first example. Only 2 variables are printed, so the ... is removed.
