llvisualize is a tool that will parse debug logs (from CDEBUG output)
and provide a graphical representation of the call graph.
Useful as a debug aid for developers.
To invoke, provide the log file as input to llvisualize.
Currently, no fancy color scheme, just the ordered call graph(on a single node)
by process ID.
Visual controls allow user to go arbitarily deep.
All fields of the CDEBUG log are available, some have been omitted from
the visual display.

To invoke:

perl llvisualize.pl < /tmp/lustre-debuglog
