 If the patterns do match the expected format, then Git will use faster hash-
 based algorithms to compute inclusion in the sparse-checkout.
 
+In the cone mode case, the `git sparse-checkout list` subcommand will list the
+directories that define the recursive patterns. For the example sparse-checkout
+file above, the output is as follows:
+
+--------------------------
+$ git sparse-checkout list
+A/B/C
+--------------------------
+
 If `core.ignoreCase=true`, then the pattern-matching algorithm will use a
 case-insensitive check. This corrects for case mismatched filenames in the
 'git sparse-checkout set' command to reflect the expected cone in the working
 directory.
 
+
+SUBMODULES
+----------
+
+If your repository contains one or more submodules, then those submodules will
+appear based on which you initialized with the `git submodule` command. If
+your sparse-checkout patterns exclude an initialized submodule, then that
+submodule will still appear in your working directory.

+# Simple Chord for Tcl
+#
+# A "chord" is a method with more than one entrypoint and only one body, such
+# that the body runs only once all the entrypoints have been called by
+# different asynchronous tasks. In this implementation, the chord is defined
+# dynamically for each invocation. A SimpleChord object is created, supplying
+# body script to be run when the chord is completed, and then one or more notes
+# are added to the chord. Each note can be called like a proc, and returns
+# immediately if the chord isn't yet complete. When the last remaining note is
+# called, the body runs before the note returns.
+#
+# The SimpleChord class has a constructor that takes the body script, and a
+# method add_note that returns a note object. Since the body script does not
+# run in the context of the procedure that defined it, a mechanism is provided
+# for injecting variables into the chord for use by the body script. The
+# activation of a note is idempotent; multiple calls have the same effect as
+# a simple call.
+#
+# If you are invoking asynchronous operations with chord notes as completion
+# callbacks, and there is a possibility that earlier operations could complete
+# before later ones are started, it is a good practice to create a "common"
+# note on the chord that prevents it from being complete until you're certain
+# you've added all the notes you need.
+#
+# Example:
+#
+#   # Turn off the UI while running a couple of async operations.
+#   lock_ui
+#
+#   set chord [SimpleChord new {
+#     unlock_ui
+#     # Note: $notice here is not referenced in the calling scope
+#     if {$notice} { info_popup $notice }
+#   }
+#
+#   # Configure a note to keep the chord from completing until
+#   # all operations have been initiated.
+#   set common_note [$chord add_note]
+#
+#   # Pass notes as 'after' callbacks to other operations
+#   async_operation $args [$chord add_note]
+#   other_async_operation $args [$chord add_note]
+#
+#   # Communicate with the chord body
+#   if {$condition} {
+#     # This sets $notice in the same context that the chord body runs in.
+#     $chord eval { set notice "Something interesting" }
+#   }
+#
+#   # Activate the common note, making the chord eligible to complete
+#   $common_note
+#
+# At this point, the chord will complete at some unknown point in the future.
+# The common note might have been the first note activated, or the async
+# operations might have completed synchronously and the common note is the
+# last one, completing the chord before this code finishes, or anything in
+# between. The purpose of the chord is to not have to worry about the order.
+
+# SimpleChord class:
+#   Represents a procedure that conceptually has multiple entrypoints that must

+# line of text it displays. Most of the time, there will be at most one
+# ongoing operation.
+#
+# Note that the entire status bar can be either in single-line or two-line
+# mode, depending on the constructor. Multiple active operations are only
+# supported for single-line status bars.
