=head1 NAME
Reply::Plugin::Packages - persist the current package between lines
=head1 VERSION
version 0.22
=head1 SYNOPSIS
  ; .replyrc
  [Packages]
  default_package = My::Scratchpad
=head1 DESCRIPTION
This plugin persists the state of the current package between lines. This
allows lines such as C<package Foo;> in the Reply shell to do what you'd
expect. The C<default_package> configuration option can also be used to set the
initial package to use when Reply starts up.
