To use under emacs, simply add the following line to your .emacs, 
then when you visit a perl file, you can use Ctrl-Return to run perl_checker
on this file

  (global-set-key [(control return)] (lambda () (interactive) (save-some-buffers 1) (compile (concat "perl_checker --restrict-to-files " (buffer-file-name (current-buffer))))))

perl_checker --restrict-to-files scanner.pm > errors.err ; vim -c ':copen 4' -c ':so /usr/share/vim/ftplugin/perl_checker.vim' -q
