NDoc2 NAnt Task - Issue with output directory

NDoc2 NAnt Task - Issue with output directory

It looks like NDoc2 treats the output directory property as relative to the location of the dynamically generated config file. So with a setting such such as:
<documenter name="MSDN-CHM">
  <property name="IncludeFavorites" value="False" />
  <property name="OutputDirectory" value="build\docs" />

The generated documents will end up in:
C:\Documents and Settings(User)\Local Settings\Temp\build\docs

Bug or by design? :)
