Changeset 407 for trunk/tools/tracertstats/tracertstats.c

Add a "realtime" statistics module. This can display stats every "n" seconds,
or every "n" packets.

Has "csv", "html" and "png" output formats currently. (png output module
really should be autoconf'd out if the required modules don't exist).

I'd like to add odoc formats, and I probably should add a "plain text" one
too.
