Licencia GPL en módulos Perl

Para cambiar la licencia a un módulo Perl de Artistic a GPL, ó construir uno bajo directamente bajo ésta última, se deben seguir los siguientes pasos:

• Incluír el siguiente párrafo en la sección LICENCE AND COPYRIGHT de la documentación de cada módulo:

  y si es un programa ó no se autoriza su uso en programas propietarios, el texto es el siguiente:

  Copyright (C) <año> <nombre e email del autor>

  Ambos están obtenidos de los documentos originales que en una distribución Debian se encuentran en /usr/share/common-licenses. Tengo dudas, eso sí, sobre si una traducción al español es actualmente válida; lo consultaré y actualizaré en breve en caso afirmativo.

• Modificar el archivo Build.PL (en caso de utilizar --perlmb--) y cambiar la licencia a la indicada:

    1 
    2 my $builder = Module::Build->new(
    3     module_name         => 'IkiWiki::Plugin::syntax',
    4     license             => 'gpl',
    5     dist_author         => '"Victor Moral" <victor@taquiones.net>',
    6     dist_version_from   => 'lib/IkiWiki/Plugin/syntax.pm',
    7     requires => {

• Si tenemos una estructura Debian para crear un paquete, modificar el archivo correspondiente (en este caso debian/copyright):

  This is the debian package for the IkiWiki-Plugin-syntax module.
  It was created by Victor Moral <victor@taquiones.net> using dh-make-perl.
  
  
  The upstream author is: "Víctor Moral" <victor@taquiones.net>.

• Anotar el cambio si es necesario en los registros del paquete/módulo/programa y reconstruir todo ello.
