Data Loader open source - latest version posted to SourceForge

Salesforce has posted the source code for Data Loader 10 on SourceForge,net, in both CVS format and in a ZIP file distribution. This new posting is a significant advance over the version of Data Loader previously available at SourceForge 18 months ago, and includes a custom web service stack built for high performance salesforce interactions. You can freely download this Java application to extend the functionality of Data Loader, or just to see a good example of how we use the Apex API to move large amounts of data in and out of the salesforce database. As with any open source software, you can redistribute this code, but please keep in mind that we only support the existing version of Data Loader, not any modified or extended versions based on the open source code.
