I found two post very useful describing modules creation from a template. I've a doubt about which of them is better:
The first source that I've found is from: Re: Simple Module Tutorial
But surfing on the web I've found this one: template-boilerplate-code-create-perl-module
our @ISA = qw(Exporter);
our @EXPORT = qw(get_time_suffix); # symbols to be exported by defa
our $VERSION = 1.00; # version number
What is more appropriate for perl version 5.20.2 (default perl on debian in jessie)?
