;; Please report bugs, suggestions, complaints and so on to
;; bug-gnu-emacs@gnu.org and pot@gnu.org (Francesco Potortì).
;; IMPROVEMENTS OVER emacs 18.xx cmacexp.el ==========================
;; - A lot of user and programmer visible changes. See above.
;; - #line directives are inserted, so __LINE__ and __FILE__ are
;; correctly expanded. Works even with START inside a string, a
;; comment or a region #ifdef'd away by cpp. cpp is invoked with -C,
;; making comments visible in the expansion.
;; - All work is done in core memory, no need for temporary files.
;; ACKNOWLEDGMENTS ===================================================
;; A lot of thanks to Don Maszle who did a great work of testing, bug
