DESCRIPTION
@ -56,6 +56,24 @@ base-name::
Write the pack contents (what would have been written to
.pack file) out to the standard output.
--revs::
Read the revision arguments from the standard input, instead of
individual object names. The revision arguments are processed
the same way as gitlink:git-rev-list[1] with `--objects` flag
uses its `commit` arguments to build the list of objects it
outputs. The objects on the resulting list are packed.
--unpacked::
This implies `--revs`. When processing the list of
revision arguments read from the standard input, limit
the objects packed to those that are not already packed.
--all::
This implies `--revs`. In addition to the list of
revision arguments read from the standard input, pretend
as if all refs under `$GIT_DIR/refs` are specifed to be
included.
--window and --depth::
These two options affects how the objects contained in
the pack are stored using delta compression. The
