+# This is covered by the same copyright/licensing terms as the rest of
+# Python.
+#
+# Shell script to build the Python shared library properly; if we haven't
+# already built the export list, we'll need to link twice (argh...) so we
+# can eliminate some unwatnted global symbols from the system glue/init
+# objects.
+#
+# This is called by the Modules/Makefile as part of $(LINKCC):
+#
+# $(LINKCC) $(LDFLAGS) $(LINKFORSHARED) $(MAINOBJ) \
+#	-L.. -lpython$(VERSION) $(MODLIBS) $(LIBS) $(SYSLIBS) -o python $(LDLAST)
+#
+# In 1.5.1 this changed to:
+#
+# $(LINKCC) $(LDFLAGS) $(LINKFORSHARED) $(MAINOBJ) \
+#	$(LIBRARY) $(MODLIBS) $(LIBS) $(SYSLIBS) -o python $(LDLAST)
+#
+# For BeOS we should set $(LINKCC) to this in configure (similar to the
+# AIX situation):
+#
+# $(srcdir)../BeOS/linkcc $(LIBRARY) $(PURIFY) $(CC) -nodup $(OPT)
+#
+# -L.. -lpython$(VERSION) will automagically pick up the shared library.
+
+# Check to make sure we know what we're doing.
