This allows for #pod setting custom dates, notices, etc. while still preserving compatibility with #pod all places where L<Software::License> is used, e.g. L<Dist::Zilla>. #pod #pod In this way, you should be able to customise some aspects of the licensing #pod messages that would otherwise be difficult to tinker, e.g. adding a note #pod in the notice, setting multiple years for the copyright notice or set multiple #pod authors and/or copyright holders. #pod #pod The license details should be put inside a file that contains different #pod sections. Each section has the following format: #pod #pod =begin :list #pod #pod = header line #pod #pod This is a line that begins and ends with two underscores C<__>. The string #pod between the begin and the end of the line is first depured of any non-word #pod character, then used as the name of the section; #pod #pod = body #pod #pod a L<Text::Template> (possibly a plain text file) where items to be #pod expanded are enclosed between double braces #pod #pod =end :list #pod #pod Each section is terminated by the header of the following section or by #pod the end of the file. Example: #pod #pod __[ NAME ]__ #pod The Foo-Bar License #pod __URL__ #pod http://www.example.com/foo-bar.txt #pod __[ META_NAME ]__ #pod foo_bar_meta #pod __{ META2_NAME }__ #pod foo_bar_meta2 #pod __[ NOTICE ]__ #pod Copyright (C) 2000-2002 by P.R.
