764 most tags and some branch tips are never updated. When a
765 repository has hundreds or thousands of tags, this
766 one-file-per-ref format both wastes storage and hurts
767 performance.</p></div>
768 <div class="paragraph"><p>This command is used to solve the storage and performance
769 problem by storing the refs in a single file,
770 <code>$GIT_DIR/packed-refs</code>. When a ref is missing from the
771 traditional <code>$GIT_DIR/refs</code> directory hierarchy, it is looked
772 up in this
773 file and used if found.</p></div>
774 <div class="paragraph"><p>Subsequent updates to branches always create new files under
775 <code>$GIT_DIR/refs</code> directory hierarchy.</p></div>
776 <div class="paragraph"><p>A recommended practice to deal with a repository with too many
777 refs is to pack its refs with <code>--all</code> once, and
778 occasionally run <code>git pack-refs</code>. Tags are by
779 definition stationary and are not expected to change. Branch
780 heads will be packed with the initial <code>pack-refs --all</code>, but
781 only the currently active branch heads will become unpacked,
782 and the next <code>pack-refs</code> (without <code>--all</code>) will leave them
783 unpacked.</p></div>

795 The command by default packs all tags and refs that are already
796 packed, and leaves other refs
797 alone. This is because branches are expected to be actively
798 developed and packing their tips does not help performance.
799 This option causes all refs to be packed as well, with the exception
800 of hidden refs, broken refs, and symbolic refs. Useful for a repository
801 with many branches of historical interests.

809 The command usually removes loose refs under <code>$GIT_DIR/refs</code>
810 hierarchy after packing them. This option tells it not to.

818 Pack refs based on a <code>glob(7)</code> pattern. Repetitions of this option
819 accumulate inclusion patterns. If a ref is both included in <code>--include</code> and
820 <code>--exclude</code>, <code>--exclude</code> takes precedence. Using <code>--include</code> will preclude all
821 tags from being included by default. Symbolic refs and broken refs will never
822 be packed. When used with <code>--all</code>, it will be a noop. Use <code>--no-include</code> to clear
823 and reset the list of patterns.

831 Do not pack refs matching the given <code>glob(7)</code> pattern. Repetitions of this option
832 accumulate exclusion patterns. Use <code>--no-exclude</code> to clear and reset the list of
833 patterns. If a ref is already packed, including it with <code>--exclude</code> will not
834 unpack it.
