Usage of DDOC_KEYWORD and DDOC_TEMPLATE_PARAM macros

[Jacob Carlborg via Digitalmars-d-learn]

I'm working on a Ddoc theme and I have trouble figuring out when the 
DDOC_KEYWORD and DDOC_TEMPLATE_PARAM macros are used. Are the compiler 
outputting them or should the developer be using those directly? If the 
compiler is outputting them, then when is it doing that?
