29 | ;; besides defining functions and variables, and in particular should | |
30 | ;; NOT initialize any window systems. | |
31 | ||
32 | ;; The main entry points to this file's features are msdos-handle-args, | |
33 | ;; msdos-create-frame-with-faces, msdos-initialize-window-system, | |
34 | ;; terminal-init-internal. The last one is not supposed to be called, | |
