Import XHTML/media content into Lenya 2.0.3

Hi --

I've got an old Cocoon-based site running on a rudimentary publication
framework I made myself. The content is XHTML Strict plus pictures
(.jpg, .gif, and .png). It's stored in a directory tree that matches
the sitetree's structure. IOW, it should be relatively simple to move
it over to Lenya 2.0.3... in theory.

However, since there are over 1000 files, it wouldn't be a lot of fun
to do manually. I checked the Wiki page on importing content [
http://wiki.apache.org/lenya/HowToContentImport ], but it looks like
it's about Lenya 1.x -- at least the structure of the content
directory doesn't match what I see in the publications I've previously
created in Lenya 2.

Is there a (relatively) simple way to migrate stuff to Lenya 2 in the
same way the Wiki page describes? (Or is the Wiki page, in fact, about
Lenya 2, and I'm just misinterpreting it?)

TIA, Petteri
