Subject: options: Make trace level adjustable
X-Git-Url: http://git.itanic.dy.fi/?p=log-plotter;a=commitdiff_plain;h=112b349d73432945d85fa5d57c283a58c5cc5d22

options: Make trace level adjustable

We already have a TRACE_DEBUG level but we can't show up the prints
there unless we are able to adjust the trace level too. Now we can.
