Bill,
Without being involved in that code at all, it seems that this could be
used to (re)create commented source code from R objects. That format seems
to correspond directly to a call in a .R file with two comments above it. A
bit weird there's no comment character there but I guess thats expected to
be in the values of the comment attribute?
Anyway, just a guess.
Best,
~G
