29 | ;; End User Interface |
30 | ;; ================== | |
31 | ;; The variable `mail-user-agent' contains a symbol indicating which | |
32 | ;; Emacs mail package end users would like to use to compose outgoing | |
72fe4615 RS |
33 | ;; mail. See that variable for details (it is no longer defined in |
34 | ;; this file). | |

36 | ;; Lisp Package Authors |
37 | ;; ==================== | |
72fe4615 RS |
38 | ;; reporter.el was written primarily for Emacs Lisp package authors so |
39 | ;; that their users can more easily report bugs. When invoked, | |
40 | ;; `reporter-submit-bug-report' will set up an outgoing mail buffer | |
41 | ;; with the appropriate bug report address, including a lisp | |
42 | ;; expression the maintainer of the package can evaluate to completely | |
43 | ;; reproduce the environment in which the bug was observed (e.g. by | |
44 | ;; using `eval-last-sexp'). This package proved especially useful | |
45 | ;; during my development of CC Mode, which is highly dependent on its | |
c71437cf | 46 | ;; configuration variables. |
bf3b07d3 RS |
47 | ;; |
48 | ;; Do a "C-h f reporter-submit-bug-report" for more information. | |
