There appears to be a problem on this page of your site. On page http://www.ginac.de/tutorial/tutorial_8.html when you click on "C++-FAQ lite", the link to http://www.cerfnet.com/~mpcline/c++-faq-lite/ gives the error: Domain name lookup failed (may be a transient error). As recommended by the Robot Guidelines, this email is to explain our robotÂ’s activities and to let you know about one of the broken links we encountered. LinkWalker does not store or publish the content of your pages, but rather uses the link information to update our map of the World Wide Web. Are these reports helpful? I'd love some feedback. If you prefer not to receive these occasional error notices please let me know.
