can somebody explain file boot/i386/pc/boot.S

[Dennis Cao]

HI guys,
I am really interested in grub. So i dig into the source code a bit. I
find that the boot program is written in AT&T assembly. I am not
familiar with this language. Can somebody explain what these lines
means?

        jmp     LOCAL(after_BPB)
        nop     /* do I care about this ??? */

Thanks:)
