## 15.2: Reporting Bugs

Bug reports help make Gri more reliable and useful for all users, so please report any bugs you find. The scheme will be familiar to you, if you've participated in open-source work before.

1. Visit the bug-tracking part of the Source Forge Gri development site, at ``http://sourceforge.net/bugs/?group_id=5511`' to see whether your bug has already been reported. You may find that it has been reported and fixed already in a new version, in which case you should archive your existing Gri version and upgrade. If the bug has been reported and not fixed, then you may still wish to add a supplemental bug report, so the author knows that this bug is of concern to you as well as the others. (Plus, reporting it this way ensures that you'll receive an email when the bug is fixed.)

2. Debugging is made easier if the problem is reduced in scope. Therefore, please reduce your application and your data to the simplest case that produces the error.

3. If you know how, please try to find the bug yourself. After all, Gri is open-source for a reason! The procedure is described in the next section (see Killing Bugs).
