615 Write the generated pack index into the specified
616 file. Without this option the name of pack index
617 file is constructed from the name of packed archive

628 When this flag is provided, the pack is read from stdin

Junio C Hamano4fdccb22010-02-19 09:58:14643 Fix a "thin" pack produced by <tt>git pack-objects --thin</tt> (see

646 pack. This option only makes sense in conjunction with --stdin.

654 Before moving the index into its final destination
655 create an empty .keep file for the associated pack file.
656 This option is usually necessary with --stdin to prevent a

697 Specifies the number of threads to spawn when resolving
698 deltas. This requires that index-pack be compiled with
699 pthreads otherwise this option is ignored with a warning.
700 This is meant to reduce packing time on multiprocessor
701 machines. The required amount of memory for the delta search
702 window is however multiplied by the number of threads.
703 Specifying 0 will cause git to auto-detect the number of CPU&#8217;s
704 and use maximum 3 threads.
