By default, when you specify a DITA topic file as input, if no map that references that topic file is present, DITA2Go generates a map for your project.
To prevent DITA2Go from generating a map:
[MapGeneration] ; GenerateMapIfMissing = Yes (default, if no map found, generate a ; ditamap with the same name and run that instead), or No GenerateMapIfMissing = No
When GenerateMapIfMissing=Yes, DITA2Go first looks for a map with the same name as the topic file, in the same directory; if found, DITA2Go processes that map. If the directory contains both a .ditamap and a .bookmap, DITA2Go uses the .bookmap. DITA2Go never overwrites an existing map file.
When GenerateMapIfMissing=No, DITA2Go processes the topic file by itself. The output will not include a TOC, and related-links will not be resolved.
