It works with the current CVS source.

In tools/odcut I just started a small OD file editor. The Perl module odfile.pm
can read OD file, write OD files and extract (out of the internal DOM tree)
the header (everything, which comes before the first <snapshot>), every single
<snapshot>, and the footer (everything, which comes after the last </snapshot>).

The next step is to take care of the always increasing sequence number and the
time stamp in a sequence of <snapshot> elements. Then I'll code a wxPerl
frontend with a slider, play backwards, pause, and play forward buttons, and a
speed scale number. Only then we can seriously think about any real features of
the OD editor.

Bye, Uwe
