install command in linux

HI,
I came through the following command : install -d /var/log/%{name} -o %{username} -g %{groupname} -m 750
what does it do ?
As on man pages what i understood is that it copies the files/folders in current directory to /var/log/%{name}
But i tried it inside a directory install -d ../tmp2 It didnt copy anything to tmp2 .

Thanks
