Specifies that a who-calls-who table be printed.
This table lists each subprogram followed by a list of the
routines it calls. This switch is equivalent to <B><A HREF="calltree.html">-calltree</A>=reference</B>.
Default = no.
<P>
The reference list omits routines
called by unused library modules. Thus it contains the same
information as for the call-tree format, namely the hierarchy of
subprogram calls, but printed in a different way. This prints out
a breadth-first traversal of the call tree whereas <B><A HREF="calltree.html">-calltree</A>=tree</B> prints
out a depth-first traversal.
