C program hierarchical listing

[Chris Dueker]

We're looking for a program that will process C source code and produce
an indented listing of the hierarchy of calls, not necessarily starting
with main().  Our source is located in many files and the program would
need to process the files we specify.

We would prefer a public-domain or freely-redistributable program with
source code available.  But...

Any recommendations?  Many Thanks in advance!

Chris
