Setting playback speed

Normally the user chooses a playback rate via the rate slider in the animation window. A trace file may set the playback rate via the set_rate_ext command:

v -t time -e set_rate_ext time update-peers?

For example:
v -t 2.5 -e set_rate_ext 20ms 1

For compatibility with earlier versions of nam, the set_rate command is also supported. Instead of specifying the step size directly, you use $10\times\log_{10} \textit{<time-in-seconds>}$. For example:

v -t 2.5 -16.9897000433602 1

In order to have more readable files, set_rate_ext is preferred.
