Subject: List supported devices, modules, decoders via --list-supported.
X-Git-Tag: sigrok-cli-0.7.0~9
X-Git-Url: https://sigrok.org/gitweb/?p=sigrok-cli.git;a=commitdiff_plain;h=6293db8aea090170eced25d6f92c348b013ea475

List supported devices, modules, decoders via --list-supported.

Move this data from -V to -L|--list-supported for usability reasons.

This fixes bug #604.
