formatter to easily check 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").
