LAYOUT=$3

I realize that D_S and LAYOUT, etc are macros. I've read the DDoc documentation and HTML, CSS, etc. but none of my research mentions the $ signs, as well as the $1 and $3. Am I missing something obvious?

See point 4 here:

https://dlang.org/spec/ddoc.html#macros


$(THING ...)

is a macro invocation. Inside the macro definition, $0 is the full text represented by "..." here. Then $1 is the text up to the first comma, $2 text from first to second comma, etc.
