Subject: mpdexec: Add "verbose" option to print commands sent to MPD.
X-Git-Url: https://git.draconx.ca/gitweb/mpdhacks.git/commitdiff_plain/5227a49aa2672e4fae2b118926fa84bb7af6fa24

mpdexec: Add "verbose" option to print commands sent to MPD.

In order to add readpicture support to the thumbnailer in addition to
albumart, we need a better way to distinguish which commands returned
what results from the server.

An easy way to do that is to just print the commands.
