The lisp scanner has been originally written by Edouard G. Parmelan, and after many years it was posthumously integrated with the main idutils code. It is intended for Lisp and Emacs Lisp files (.lisp, .el, .elc, .scm). No options are currently available for this scanner.
This scanner is considered experimental; please report any problems you should encounter to ‘bug-idutils@gnu.org’ .
