This module provides an attribute wrapper around Getopt::Long.
Instead of declaring the options in a hash with references to the
variables and subroutines affected by the options, you can use the
Getopt attribute on the variables and subroutines directly.
As you can see from the Synopsis, the attribute takes an argument of
the same format as you would give as the hash key for Getopt::Long.
See the Getopt::Long manpage for details.
