Subject: New --probe-group option
X-Git-Tag: sigrok-cli-0.5.0~75
X-Git-Url: https://sigrok.org/gitweb/?p=sigrok-cli.git;a=commitdiff_plain;h=dd671ce797d8eb49d7d883df3ae65145033607cf

New --probe-group option

Devices that don't use probe groups don't need this option at all;
it only needs to be specified when using a device that has probe
groups, and then only for options that require it.
