Of course, otherwise it wouldn't work! :-)

By hand. The reference manual has more detail (Grammar/Grammar doesn't
say anything about what a STRING is, or other literals) and presents
some rules in a more readable form which wouldn't work for
Grammar/Grammar given the LL1 constraints of pgen. It also chooses
more readable names. But the translation process is fallible.
