22 | ;;; Commentary: | |
23 | ;; | |
24 | ;; Provide a special project type just for Emacs, cause Emacs is special. | |
25 | ;; | |
26 | ;; Identifies an Emacs project automatically. | |
27 | ;; Speedy ede-expand-filename based on extension. | |
28 | ;; Pre-populates the preprocessor map from lisp.h | |
29 | ;; | |
30 | ;; ToDo : | |
31 | ;; * Add "build" options. | |
32 | ;; * Add texinfo lookup options. | |
33 | ;; * Add website | |
