 ### Imports
 
 In _Coedit_, _DCD_ relies on the [library manager][lnk_widg_lib] entries and on the project parameters.

+If the [_libman_][lnk_widg_lib] is empty then the the scope of DCD is limited to the current module or the to the current project sources and imports.
 To prevent that, it's absolutely necessary to add at least _phobos_ and _core_ to the [_libman_][lnk_widg_lib] (if not automatically done the first time CE is executed).
 
 _DCD_ also has a native configuration system. Refer to the official [_Readme_](https://github.com/Hackerpilot/DCD#configuration-files).
