=head1 DESCRIPTION

Many times there is a group of subroutines that can be tailored by
different situations with a few, say global variables.
However, global variables pollute namespaces, become mangled
when the functions are multi-threaded and probably have many 
other faults that it is not worth the time discovering.

As well documented in literature, object oriented programming do not have
these faults.
This program module class of objects provide the objectized options
for a group of subroutines or encapsulated options by using
the methods directly as in an option object.

The C<Data::Startup> class provides a way to input options
in very liberal manner of either
