Importing and Exporting

Module can provide subroutines and variables to its user:

use Hello; # default list use Hello qw(greet abandon); # just those use Hello (); # nothing at all

Inside the module:

use Exporter; @ISA = qw(Exporter);

@EXPORT = qw(smile greet handshake); @EXPORT_OK = qw(wave farewell abandon);
