 git-pack-objects(1) Manual Page
 </h1>
 <h2>NAME</h2>
 <div class="sectionbody">
 <p>git-pack-objects -
  Create a packed archive of objects
 </p>
 </div>
 </div>
 <h2>SYNOPSIS</h2>
 <div class="sectionbody">
 <div class="verseblock">
 <div class="content"><em>git-pack-objects</em> [-q] [--no-reuse-delta] [--non-empty]
  [--local] [--incremental] [--window=N] [--depth=N]
  {--stdout | base-name} &lt; object-list</div></div>
 </div>
 <h2>DESCRIPTION</h2>
 <div class="sectionbody">
 <p>Reads list of objects from the standard input, and writes a packed
 archive with specified base-name, or to the standard output.</p>
 <p>A packed archive is an efficient way to transfer set of objects
 between two repositories, and also is an archival format which
 is efficient to access. The packed archive format (.pack) is
 designed to be unpackable without having anything else, but for
 random access, accompanied with the pack index file (.idx).</p>
 <p><em>git-unpack-objects</em> command can read the packed archive and
 expand the objects contained in the pack into "one-file
 one-object" format; this is typically done by the smart-pull
 commands when a pack is created on-the-fly for efficient network
 transport by their peers.</p>
 <p>Placing both in the pack/ subdirectory of $GIT_OBJECT_DIRECTORY (or
 any of the directories on $GIT_ALTERNATE_OBJECT_DIRECTORIES)
 enables git to read from such an archive.</p>
 <p>In a packed archive, an object is either stored as a compressed
 whole, or as a difference from some other object. The latter is
 often called a delta.</p>
 </div>
 <h2>OPTIONS</h2>
 <div class="sectionbody">
 <dl>
 <dt>
 base-name
 </dt>
 <dd>
 <p>
  Write into a pair of files (.pack and .idx), using
  &lt;base-name&gt; to determine the name of the created file.
  When this option is used, the two files are written in
  &lt;base-name&gt;-&lt;SHA1&gt;.{pack,idx} files. &lt;SHA1&gt; is a hash
  of object names (currently in random order so it does
  not have any useful meaning) to make the resulting
  filename reasonably unique, and written to the standard
  output of the command.
 </p>
 </dd>
 <dt>
 --stdout
 </dt>
 <dd>
 <p>
  Write the pack contents (what would have been written to
  .pack file) out to the standard output.
 </p>
 </dd>
 <dt>
 --window and --depth
 </dt>
 <dd>
 <p>
  These two options affects how the objects contained in
  the pack are stored using delta compression. The
  objects are first internally sorted by type, size and
  optionally names and compared against the other objects
  within --window to see if using delta compression saves
  space. --depth limits the maximum delta depth; making
  it too deep affects the performance on the unpacker
  side, because delta data needs to be applied that many
  times to get to the necessary object.
 </p>
 </dd>
 <dt>
 --incremental
 </dt>
 <dd>
 <p>
  This flag causes an object already in a pack ignored
  even if it appears in the standard input.
 </p>
 </dd>
 <dt>
 --local
 </dt>
 <dd>
 <p>
  This flag is similar to <tt>--incremental</tt>; instead of
  ignoring all packed objects, it only ignores objects
  that are packed and not in the local object store
  (i.e. borrowed from an alternate).
 </p>
 </dd>
 <dt>
 --non-empty
 </dt>
 <dd>
 <p>
  Only create a packed archive if it would contain at
  least one object.
 </p>
 </dd>
 <dt>
 -q
 </dt>
 <dd>
 <p>
  This flag makes the command not to report its progress
  on the standard error stream.
 </p>
 </dd>
 <dt>
 --no-reuse-delta
 </dt>
 <dd>
 <p>
  When creating a packed archive in a repository that
  has existing packs, the command reuses existing deltas.
  This sometimes results in a slightly suboptimal pack.
  This flag tells the command not to reuse existing deltas
  but compute them from scratch.
