+To help keep track and organize all issues are a group of tireless
+volunteers collectively known as the @emph{Bug Squad}. Composed mainly

+
+@itemize
+
+@item
+Monitoring the LilyPond Bugs mailing list looking for any issues
+reported by other users ensuring that they are accurate and contain
+enough information for the developers to work with, preferably with
+@rweb{Tiny examples} and if applicable, screenshots.
+
+@item
+Adding new issues to the @emph{issue tracker} or updating existing
+issues with new information.
+
+@item
+Verifying issues in the @emph{issue tracker} that have been marked
+as @q{fixed}; making sure either that the fix works or (in the case of
+Documentation for example) has at least been commited to the code base.
-@qq{Issues} isn't just a politically-correct term for @qq{bug}.
-We use the same tracker for feature requests and code TODOs, so
-the term @qq{bug} wouldn't be accurate. Despite the difference
-between @qq{issue} and @qq{bug}, we call our team of contributors
-who organize issues the @emph{Bug Squad}.

+accurately reflect the input (e.g. where the user would expect
+an accidental, but none is shown) or which produces aesthetically
+poor output in a situation which could be expected to crop up
+frequently in real-world music. It should not be used where the
+problem can be avoided with a simple workaround. It can also

-@section Finding the cause of a regression
+@subsubheading Patches to review
-@warning{This is not a @qq{simple} task; it requires a fair amount
-of technical knowledge.}
+Patches which have no @qq{obvious} problems:
-Git has special functionality to help tracking down the exact
-commit which causes a problem. See the git manual page for
-@code{git bisect}. This is a job that non-programmers can do,
-although it requires familiarity with git, ability to compile
-LilyPond, and generally a fair amount of technical knowledge. An
-in-depth explanation of this process will not be given here.
-
-Even if you are not familiar with git or are not able to compile
-LilyPond you can still help to narrow down the cause of a
-regression simply by downloading the binary releases of different
-LilyPond versions and testing them for the regression. Knowing
-which version of LilyPond first exhibited the regression is
-helpful to a developer as it shortens the @code{git bisect}
-procedure described above.
+@example
+@uref{http://code.google.com/p/lilypond/issues/list?can=2&q=label:patch-review}
+@end example
-Once a problematic commit is identified, the programmers' job is
-much easier. In fact, for most regression bugs, the majority of
-the time is spent simply finding the problematic commit.
-More information is in @ref{Regression tests}.
