+# The ZDS-II compiler and assembler both generate object files in the

+# extension.  The build system expects these behaviors when compiling some
+# file, say foo.c:
+#
+# 1. If the foo.obj object belongs in a lower level directory (such as bin/),
+#    then the relative path will be preface the object file name (such as
+#    bin/foo.obj)).  In this case, the build system will call MOVEOBJ to
+#    move the objects in place and nothing special need be done here.
+# 2. In other cases, the build system may decorate the object file name such
+#    as a.b.c.foo.obj.  This case is distinguished here by because does not
+#    lie in a lower directory, but lies in the current directory and is
