<!--mksite:expandvars--> <!--mksite:noexpandvars-->
The option can be selected in the sitefile, per default we do expand direct comment variables. <!--mksite:nocommentvars--> disables this feature as well.

This is the preferred method of expanding variables. They are
invisible in the source htm file. They add some text to the
result. The variant expansions can be selected via "?" after
the variable name. The variant expansion has always (a) the
lowercased variant of the original value and (b) any markup
removed from the original value. That makes it most usueful
to be pasted into <title> tag contents.
The direct usage of the variant name (without even some whitspace inside the comment markup) makes for an additional modification where the variant is usually (a) hyphenated for toplevel variables or (b) parenthesed for secondary variables. The toplevel variables are "DC.title" and "DC.author" that can be selected as "$title" and "$author". The secondary variables are usually those of "DC.date", e.g. "DC.date.modified" and "DC.date.issued" that can be selected as "$modified" and "$issued".
The specification of variants stems from times when there was
no complex expansion of variables available that would allow
additional formatting within the comment box. See the
simplevars for those. Therefore
the most common formatting was done in the mksite.sh script
making for the usual editing of those values. The variant
expansions have survived can still be used in that mode and
make sometimes for a little shorter input text, e.g. for
<title> content specs.
