cflow equiv. for c++ (on Unix)

[Bill Toner]

I've been searching for awhile for a tool that will return a call graph,
similar to how cflow works with C code, only I need something to work on
C++ files. I need to determine the call graph dynamically from a Perl
script, so graphical output doesn't do me much good. Preferable some sort
of indented output that Perl can parse through would be great (similar to
what cflow does).

Thanks for any help.
