+## this function removes the PKG_ADD script from the .oct directory of the io
+## package after installation. The reason is that PKG_ADD calls chk_spreadsheet_support
+## which belongs to the io package itself. While it is ok when called from the
+## .m directory (since chk_spreadsheet_support is there), when called from the
+## .oct directory it fails since the package hasn't been loaded yet
