+# Generate a link-dependency graph
+# Given a baseline list of components, look through the BLDMAKE
+# generated files to find the individual DLL and EXE makefiles.
+# Scan those makefile to find out which .LIB files are generated,
+# and which .LIB files are required, thereby deducing the 
+# component dependency graph.
