Teach Git how to prompt the user for a good bug report: reproduction
steps, expected behavior, and actual behavior. Later, Git can learn how
to collect some diagnostic information from the repository.
If users can send us a well-written bug report which contains diagnostic
information we would otherwise need to ask the user for, we can reduce
the number of question-and-answer round trips between the reporter and
the Git contributor.
Users may also wish to send a report like this to their local "Git
expert" if they have put their repository into a state they are confused
by.

+git-bugreport(1)
+================
+
+NAME
+----
+git-bugreport - Collect information for user to file a bug report
+
+SYNOPSIS
+--------
+[verse]
+'git bugreport' [(-o | --output-directory) <path>] [(-s | --suffix) <format>]
+
+DESCRIPTION
+-----------
+Captures information about the user's machine, Git client, and repository state,
+as well as a form requesting information about the behavior the user observed,
+into a single text file which the user can then share, for example to the Git
+mailing list, in order to report an observed bug.
+
+The following information is requested from the user:
+
+ - Reproduction steps
+ - Expected behavior
+ - Actual behavior
+
+This tool is invoked via the typical Git setup process, which means that in some
+cases, it might not be able to launch - for example, if a relevant config file
+is unreadable. In this kind of scenario, it may be helpful to manually gather
+the kind of information listed above when manually asking for help.
+
+OPTIONS
+-------
+-o <path>::
+--output-directory <path>::
+ Place the resulting bug report file in `<path>` instead of the root of
+ the Git repository.
+
+-s <format>::
+--suffix <format>::
+ Specify an alternate suffix for the bugreport name, to create a file
+ named 'git-bugreport-<formatted suffix>'. This should take the form of a
+ link:strftime[3] format string; the current local time will be used.
+
+GIT

+Part of the linkgit:git[1] suite
