ShowMarks.vim is a Vim plugin which provides a visual representation of location marks. I've written an ebuild which uses the standard vim eclasses. I'm attaching the ebuild and the source tar.bz2 (because of the way vim.sf.net handles downloads, I believe the source has to go on the gentoo mirrors?). The plugin is public domain. I've tested on x86 and sparc; I don't have access to other archs.
