site moved September 7 2009
The web site has been moved to a different server, and you may suffer from some glitches due to this until everything has been fixed to work properly at the new location. Please have patience.


  • All the stuff under "/lxr/" is no longer working. The libcurl examples were the most used links in there but they are now remade differently - and quite honestly in a nicer way too.
