This package is obsolete. Since version 22.1 Emacs has built-in support for themes. That implementation does not derive from the implementation provided by this package. Back when this was new we referred to the new implementation as `deftheme' themes, as opposed to `color-theme' themes. This package comes with a large collection of themes. If you still use it because you want to use one of those, then you can never-the-less migrate to the "new" theme implementation. The `color-theme-modern' package ports all themes that are bundles with `color-theme' to the `deftheme' format. It also ports a few third-party themes. Its documentation contains setup instructions. Don't forget to uninstall `color-theme'. ; Thanks Deepak Goel S. Pokrovsky for ideas and discussion. Gordon Messmer for ideas and discussion. Sriram Karra for the color-theme-submit stuff. Olgierd `Kingsajz' Ziolko for the spec-filter idea. Brian Palmer for color-theme-library ideas and code All the users that contributed their color themes.
