29 ;; Reproduce XEmacs bugs, so that they can get fixed.
30 ;; Especially, make XEmacs crash.
31 ;; You may need to use a debug version of XEmacs to reproduce some of these.
32
33 ;; Several global keybindings are created, each of which exhibits a bug.
34
35 ;; For XEmacs maintainers and other masochists.
36
37 ;; It's a bad idea to rely on code in this file continuing to work in
38 ;; the same way. :-)
