+===== Documentation for the PDFtalk library =====
 The {{pdf:pdf32000_2008.pdf|PDF specification}} is extensive. The implementation covers the core mechanisms to read and write PDF objects in a conforming way. This is comparable to the virtual machine and core classes in Smalltalk. Many of the PDF features and possibilities are implemented by sets of PDF types and a clear definition of their structure and interplay. This compares to class libraries in Smalltalk.

+==== About the library ====
+  * [[Implementation]] Notes the state of the implementation of the features structured along the specification chapters.
+  * [[Typing]] PDF attributes are typed. To make use of this, the typing system was implemented. Since this is complex, it deserves its own topic.
+  * [[Extending]] How to add a new PDF Object to the library from the specification.
