Does the w3compiler product work with FrontPage, Dreamweaver, etc.?
Yes. You can use the product with any markup generated by editors. Direct integration is also possible using the command line version of the w3compiler. An interim 1.x generation release will automate the setup of this process for Dreamweaver. However, because optimization is much better for a whole site at a time, we encourage developers to work with the w3compiler in that fashion rather than saving and optimizing a page at a time from an editor.
