--| @SUMMARY Displays a hierarchical list of the subprograms called by
--| any subprogram. This display can be a batch listing, or an
--| interactive hierarchy.
--| @DESCRIPTION This package provides a simple yet useful tool for
--| analyzing the call tree for a program. It contains two interfaces:
--| a batch listing and an interactive display.
--|
--| Possible future enhancements:
--| Handling of generic instantiations
--| Better handling of recursive calls
--| Incorporating the Rational error-handling model
--|
--| @INDICES (References, Analysis, Command_Interface)
--| @SPECIAL_NOTES Both procedures must be called with names of subprograms.
--| The program does not handle package names by themselves.
package Call_Trees is
--| @DESCRIPTION This procedure provides a batch listing of the call
--| tree for a given subprogram. The listing indents to show
--| levels. If a subprogram is listed more than once, it will
--| only be broken down the first time. If a subprogram calls
--| another subprogram more than once, the called subprogram will
--| appear more than once in the listing.
--| @PARAMETERS These_Objects => If the string resolves to more than
--| one object, the listing will contain the call tree for each
--| valid object.
procedure List (These_Objects : in String := "<SELECTION>");
--| @DESCRIPTION This procedure provides an interactive browsing
--| mechanism for the call tree of a subprogram. The window
--| that appears will look something like this:
--|
--| __| CALLER_ONE
--| | | CALLER_TWO
--| |
--| ------------------ --------
--| | MY_SUBPROGAM | | QUIT |
--| ------------------ --------
--| |
--| |__| CALLS_THIS_ONE
--| | THIS_ONE_TWO
--|
--| As you can see, the window shows the current subprogram name,
--| the subprograms that call it, and the subprograms that it
--| calls. You can use the following keys to maneuver through
--| the hierarchy: DEFINITION, UP, DOWN, LEFT, RIGHT.
--| @PARAMETERS This_Object => Since the procedure provides an
--| interactive display, it can only be called with one object
--| at a time.
procedure Visit (This_Object : in String := "<SELECTION>");
