clone: --naked option.
The new option --naked is to help creating a naked repository for public consumption. $ git clone -l -s --naked \ /pub/scm/.../torvalds/linux-2.6.git subproj-2.6.git is equivalent to this sequence: $ git clone -l -s -n /pub/scm/.../torvalds/linux-2.6.git temp $ mv temp/.git subproj-2.6.git $ rmdir temp Signed-off-by: Junio C Hamano <junkio@cox.net>

-n::
|

No checkout of HEAD is performed after the clone is complete.
|
||||
|
||||
--naked::
|
||||
Make a 'naked' GIT repository. That is, instead of
|
||||
creating `<directory>` and placing the administrative
|
||||
files in `<directory>/.git`, make the `<directory>`
|
||||
itself the `$GIT_DIR`. This implies `-n` option.
|
||||
|
||||
-o <name>::
|
||||
Instead of using the branch name 'origin' to keep track
|
||||
of the upstream repository, use <name> instead. Note
