formatter to easy checking the spelling of POD

 Pod::Spell is a POD formatter whose output is good for checking the spelling
 of the document. Pod::Spell is much like Pod::Text, except that it doesn't
 put much effort into actual formatting, and it suppresses things that look
 like Perl symbols or Perl jargon (so that your spellchecking program won't
 complain about mystery words like "`$thing'" or "`Foo::Bar'" or "hashref").
