New STEP utility: step2vpl
It mostly works... mostly. :)

Well, we either need to build a 'filter' object to convert RTF+STEP to
every frontend markup that we want to support (currently how our engine
works), or to an 'intermediate' markup-- probably ThML-- and let each
frontend build a ThMLToWhateverTheirFrontendNeeds Filter.
This will be our new 2 phase Filter architecture.

Yes, I'd love to see how you handle some of the quirks that I've run up
The docs just flat out aren't correct, from what I've seen. But for the
most part they aren't too hard to follow (which I suppose is good. At
least I can QUICKLY get to where I know the docs are slightly wrong) :)

Yes. Our engine treats Bibles are verse granular repositories. It will
be interesting to see how tough it is to get a STEP Bible to display the
same as our other modules. We will probably then also have a special
'STEP view' that will show for module formatted in its 'STEP Viewable
chunk' granularity also.

I've read the 'preview of 2.0' section on the BSISG site and it doesn't
give me any good technical information about how to treat Bibles
differently than any other module. What our engine really needs the
ability to do is to, eg. GetTheTextFor("James 1:19"). This is not a
trivial task unless there is something special they do to tell me the
OFFSET into the viewable chunk for the verse, and the LENGTH of the
the free NKJV STEP module that Parsons has on their site
(ftp://download.parsonstech.com/demos/qnkjo.exe) has the Vsync.idx index
referencing every verse in the Bible (or as far as I can tell). I used
this index for the step2vpl utility. It seems to end prematurely in
Rev., though. Maybe my loops are off...
Well, glad we're both making progress. I'm excited to see what you
have! I have no interest in making a step module writer! I'm glad you

some comments on the subject there. We'd love to have you and the
