Importing RCS (and SCCS) into SVN?

I'm in a state of paralysis, wondering how to import my RCS setup into SVN.
I also have some SCCS files that I would like to import into SVN, but I
have a good SCCS to RCS tool which I can use first if RCS works easily
(it's an extension of (an old version of) the standard sccs2rcs script).

I'll explain my scenario in detail if people are interested, but I'd like
to know if anyone has experimented with importing RCS files with no CVS
around.

(Very briefly: I have multiple source directories, each with its own RCS
sub-directory. And the history goes back to 1988 or so - originally via
SCCS, later converted to RCS. The volume is not outrageous; it would be
measured MB, not GB. And only a few files have any branches, which greatly
simplifies my life. I am also wondering about directory layouts, but that
requires a more extensive discussion of how I do things.)

If necessary, I'll work off cvs2svn, adapting that to Perl (I'm not
sufficiently Python-literate to want to work in it), and adapting it to RCS
and/or SCCS as seems best. But I'd like to hear what anyone else has done
in this area - if, indeed, anyone has done anything.

[I subscribe to the digest; if you don't Cc me, I won't be able to respond
until I see the message in the next digest.]
