 This is the next more general version of the [[GemstoneFileout|Gemstone Fileout]] project.
-The only working example is the PDFtalk port from VisualWorks to Gemstone.
+A working example is the PDFtalk port from VisualWorks to Gemstone.
 It is intended to cover other dialects (Squeak, Pharo, VAST, (Smalltalk/X; has namespaces)) as well.
 [Begin of 2022] There is the possibility for a project to implement a general port for non-namespace Smalltalk dialects. A **[[PDFtalkNonNamespaceFileout|project page is setup here]]**.
+The [[SmalltalkTransformDocumentation|Smalltalk transform documentation]] describes all the technical details.
