You should also mention 

@EXPORT_OK = qw(...);         # symbols to export on request

Reserve @EXPORT only for those routines which are MOST used.  Things 
which are useful, but not required belong in @EXPORT_OK.  People writing 
modules should read perlmod.pod, perlmodlib.pod and the pod for 
Exporter.pm.

Additionally, routines inside modules should not call die().

Instead you're advised to apply the Carp module

use Carp;

and convert each instance of die() to croak(). From the pod:
