dotless Configuration Options

Unless my googling is failing me, I can't find any documentation on the dotless configuration for Web.Config, so I've gone through the code, I think I understand the different options

• minifyCss
• true or false
• Minifies the CSS output
• cache
• true or false
• Caches the CSS after being created
• web
• true or false
• if true, this uses http specifc options,  must be set when using on the web,  Response.Cache, Request.QueryString for parameters, Server.MapPath for mapping, puts the Log Messages in the Response
• if false, uses in memory cache, uses console logger,  uses paramaters from the console, 
• log
• info, debug, warn, error, default
• optimization
• 0-n
• Optimizes the output...
• source
• How dotless reads the files of interface IFileReader, its the type usually FileReader but can be VirtualFileReader which uses HostingEnvironment.VirtualPathProvider
• logger
• Can be set but then gets overidden by the "web" boolean, there are AspNetTraceLogger (HttpContext.Trace.Write), aspResponseLogger (Response.Write as Css), ConsoleLogger (Console.Write), DiagnosticsLogger (Debug.WriteLine) and NullLogger (Swallows).

  <dotless minifyCss="false" cache="false" web="true" log="debug"
           optimization="10" 
           logger="dotless.Core.Loggers.AspNetTraceLogger" />
