" Vim color file
" Maintainer: Martin Baeuml <baeuml@gmail.com>
" Last Change: 2008-02-09
"
" This color file is a modification of the "summerfruit" color scheme by Armin Ronacher
" so that it can be used on 88- and 256-color xterms. The colors are translated
" using Henry So's programmatic approximation of gui colors from his "desert256"
" color scheme.
"
" I removed the "italic" option and the background color from
" comment-coloring because that looks odd on my console.
"
" The original "summerfruit" color scheme and "desert256" are available from vim.org.
