export forces the listed symbols into the callers namespace. export_ok allows the listed symbols to be pulled into the callers namespace. export_ok is nicer as it gives the user of your module the choice. See Exporter for details.

Exports pollute the namespace of the module user. If you must export try to use @EXPORT_OK in preference to @EXPORT and avoid short or common symbol names to reduce the risk of name clashes.
