4638 | PLEASE FOLLOW THESE PROCEDURES | |
4639 | ------------------------------ | |
4640 | ||
4641 | Before reporting a bug, please verify that it is related to Viper, and is | |
4642 | not cause by other packages you are using. | |
4643 | ||
4644 | Don't report compilation warnings, unless you are certain that there is a | |
4645 | problem. These warnings are normal and unavoidable. | |
4646 | ||
4647 | Please note that users should not modify variables and keymaps other than | |
4648 | those advertised in the manual. Such `customization' is likely to crash | |
4649 | Viper, as it would any other improperly customized Emacs package. | |
4650 | ||
4651 | If you are reporting an error message received while executing one of the | |
4652 | Viper commands, type: | |
4653 | ||
4654 | M-x set-variable <Return> debug-on-error <Return> t <Return> | |
4655 | ||
4656 | Then reproduce the error. The above command will cause Emacs to produce a | |
4657 | back trace of the execution that leads to the error. Please include this | |
4658 | trace in your bug report. | |
4659 | ||
4660 | If you believe that one of Viper's commands goes into an infinite loop | |
4661 | \(e.g., Emacs freezes\), type: | |
4662 | ||
4663 | M-x set-variable <Return> debug-on-quit <Return> t <Return> | |
4664 | ||
4665 | Then reproduce the problem. Wait for a few seconds, then type C-g to abort | |
4666 | the current command. Include the resulting back trace in the bug report. | |
