+NetBeans does not allow changes in read-only files
+		Vim normally allows changes to a read-only file and only
+		enforces the read-only rule if you try to write the file.
+		However, NetBeans does not let you make changes to a file
+		which is read-only and becomes confused if vim does this.
+		So vim does not allow modifications to files when run with
+		NetBeans.
