[Mono-list] how to get relative path

Right, but beware that you have to do some post-processing
on the Codebase return value to get it to work as a
local path, especially if you want it to work on both
Linux and Windows. Here's what I use, in case it's helpful
to anyone:

        public static string GetAssemblyPath(Assembly assembly)
            string path = assembly.CodeBase;
            Uri uri = new Uri(path);

            // If it wasn't loaded locally, use the Location
            if (!uri.IsFile)
                return assembly.Location;

            if (uri.IsUnc)
                return path.Substring(Uri.UriSchemeFile.Length + 1);

            int start = Uri.UriSchemeFile.Length +

            if (path[start] == '/' && path[start + 2] == ':')

            return path.Substring(start);
