journalling (traditional UNIX filesystems) or that only journal metadata
and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
+core.preloadindex::
+ Enable parallel index preload for operations like 'git diff'
++
+This can speed up operations like 'git diff' and 'git status' especially
+on filesystems like NFS that have weak caching semantics and thus
+relatively high IO latencies. With this set to 'true', git will do the
+index comparison to the filesystem data in parallel, allowing
+overlapping IO's.
+
+core.notesRef::
+ When showing commit messages, also show notes which are stored in
+ the given ref. This ref is expected to contain paths of the form
+ ??/*, where the directory name consists of the first two
+ characters of the commit name, and the base name consists of
+ the remaining 38 characters.
++
+If such a path exists in the given ref, the referenced blob is read, and
+appended to the commit message, separated by a "Notes:" line. If the
+given ref itself does not exist, it is not an error, but means that no
+notes should be print.
++
+This setting defaults to "refs/notes/commits", and can be overridden by
+the `GIT_NOTES_REF` environment variable.
+
alias.*::
Command aliases for the linkgit:git[1] command wrapper - e.g.
after defining "alias.last = cat-file commit HEAD", the invocation
Context` menu item is invoked from 'git gui blame'. If this
variable is set to zero, the whole history is shown.
+guitool.<name>.cmd::
+ Specifies the shell command line to execute when the corresponding item
+ of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
+ mandatory for every tool. The command is executed from the root of
+ the working directory, and in the environment it receives the name of
+ the tool as 'GIT_GUITOOL', the name of the currently selected file as
+ 'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
+ the head is detached, 'CUR_BRANCH' is empty).
+
+guitool.<name>.needsfile::
+ Run the tool only if a diff is selected in the GUI. It guarantees
+ that 'FILENAME' is not empty.
+
+guitool.<name>.noconsole::
+ Run the command silently, without creating a window to display its
+ output.
+
+guitool.<name>.norescan::
+ Don't rescan the working directory for changes after the tool
+ finishes execution.
+
+guitool.<name>.confirm::
+ Show a confirmation dialog before actually running the tool.
+
+guitool.<name>.argprompt::
+ Request a string argument from the user, and pass it to the tool
+ through the 'ARGS' environment variable. Since requesting an
+ argument implies confirmation, the 'confirm' option has no effect
+ if this is enabled. If the option is set to 'true', 'yes', or '1',
+ the dialog uses a built-in generic prompt; otherwise the exact
+ value of the variable is used.
+
+guitool.<name>.revprompt::
+ Request a single valid revision from the user, and set the
+ 'REVISION' environment variable. In other aspects this option
+ is similar to 'argprompt', and can be used together with it.
+
+guitool.<name>.revunmerged::
+ Show only unmerged branches in the 'revprompt' subdialog.
+ This is useful for tools similar to merge or rebase, but not
+ for things like checkout or reset.
+
+guitool.<name>.title::
+ Specifies the title to use for the prompt dialog. The default
+ is the tool name.
+
+guitool.<name>.prompt::
+ Specifies the general prompt string to display at the top of
+ the dialog, before subsections for 'argprompt' and 'revprompt'.
+ The default value includes the actual command.
+
help.browser::
Specify the browser that will be used to display help in the
'web' format. See linkgit:git-help[1].
