+" Vim color file
+" Maintainer: Henry So, Jr. <henryso@panix.com>
+
+" These are the colors of the "desert" theme by Hans Fugal with a few small
+" modifications (namely that I lowered the intensity of the normal white and
+" made the normal and nontext backgrounds black), modified to work with 88-
+" and 256-color xterms.
+"
+" The original "desert" theme is available as part of the vim distribution or
+" at http://hans.fugal.net/vim/colors/.
+"
+" The real feature of this color scheme, with a wink to the "inkpot" theme, is
+" the programmatic approximation of the gui colors to the palettes of 88- and
+" 256- color xterms. The functions that do this (folded away, for
+" readability) are calibrated to the colors used for Thomas E. Dickey's xterm
+" (version 200), which is available at http://dickey.his.com/xterm/xterm.html.
+"
+" I struggled with trying to parse the rgb.txt file to avoid the necessity of
+" converting color names to #rrggbb form, but decided it was just not worth
+" the effort. Maybe someone seeing this may decide otherwise...
