problem with the crawler as the tutorial said

[arilishu]

With this code:
CrawlConfiguration crawlConfig = new CrawlConfiguration();
crawlConfig.CrawlTimeoutSeconds = 100;
crawlConfig.MaxConcurrentThreads = 10;
crawlConfig.MaxPagesToCrawl = 1000;
crawlConfig.UserAgentString = "abot v1.0 http://code.google.com/p/abot";
//crawlConfig.ConfigurationExtensions.Add("SomeCustomConfigValue1", "1111");
//crawlConfig.ConfigurationExtensions.Add("SomeCustomConfigValue2", "2222");
PoliteWebCrawler crawler = new PoliteWebCrawler(crawlConfig, null, null, null, null, null, null, null);

This is the error:
Error 1 The best overloaded method match for 'Abot.Crawler.PoliteWebCrawler.PoliteWebCrawler(Abot.Poco.CrawlConfiguration, Abot.Core.ICrawlDecisionMaker, Abot.Util.IThreadManager, Abot.Core.IScheduler, Abot.Core.IPageRequester, Abot.Core.IHyperLinkParser, Abot.Util.IMemoryManager, Abot.Core.IDomainRateLimiter, Abot.Core.IRobotsDotTextFinder)' has some invalid arguments

Thanks, updated the documentation for the extra null that is needed.
