: ==================================
: @Utils::ISA = qw(Exporter);
This allows the Exporter subroutines to be used by this module
as if they were defined in this module.
: @Utils::EXPORT = qw(set_verbose vprint logmsg
: convert_size ip2int int2ip
: time2str);
This forces these subroutines to be imported by default into the
calling packages name space.

According to the docs, it is actually a frowned upon practice to
automatically export anything. Without the second statement above,
no functions would automatically be exported.
: I dont have any clue whats the significance of ISA.
I think it is called Class Inheritance.
: What perldoc shall I see for help on this?
Read the Exporter.pm docs. Also in perlmod read the
"Perl Classes" section.
