Since 2001 I have been the author and maintainer of the Linux tool efibootmgr, which is used to edit the boot menu on EFI and UEFI-capable systems. It hasn't needed much maintenance for several years, as it "just works" and there aren't many systems that use EFI yet. But I do get patches every now and again to review.
To make it simpler for people to contribute to efibootmgr, I've now posted it in a GIT repository at http://linux.dell.com/git/efibootmgr.git.
