Gurus,

We have “gr\_modtool disable ABC” to disable the ABC custom block.  
But how to enable it back?  
(There is no “gr\_modtool enable” or equivalent).

Huh, I thought I’d put that in there. Well, seems I haven’t.

In any case, ‘disable’ simply comments out all relevant files in the  
CMakeLists.txt (and other places). You can undo that pretty easily.

That is very clear.  
Thank you very much.
