Zope products are components written in Python that can be installed to be used in Zope. After installing a new Zope product, you can create instances of this product. Creating an instance of a product means creating a new object in Zope. An object, for example, can be a folder, a DTML method, or a whole application depending on the product installed.
The Zope community provides hundreds of free Zope products that are divided into categories such as External Access, User Management, or Navigational. The products are free to download either from the download page at www.zope.org, or you may want to check www.zope-treasures.com.
