[dpdk-dev] [PATCH 4/4] doc/guides: suppress printing out standard output

[Bruce Richardson <bruce.richardson@intel.com>]

To see only errors and warnings from the doc builds, we can send the
standard output text to a logfile and have only the stderr messages
printed. This is similar to what is done for the API documentation.
