60 Reporting Bugs
Sometimes you will encounter a bug in Emacs. Although we cannot
promise we can or will fix the bug, and we might not even agree that it
is a bug, we want to hear about problems you encounter. Often we agree
they are bugs and want to fix them.
To make it possible for us to fix a bug, you must report it. In order
to do so effectively, you must know when and how to do it.
Before reporting a bug, it is a good idea to see if it is already
known. You can find the list of known problems in the file
etc/PROBLEMS in the Emacs distribution; type C-h C-e to read
it. Some additional user-level problems can be found in Bugs and problems. Looking up your
problem in these two documents might provide you with a solution or a
work-around, or give you additional information about related issues.
