don't worry. As a matter of fact I was ill most of last week, and I'm still 
busy catching up on all my real life tasks. So you certainly were not / are 
not holding anything up.

I'll yet have to look at it in detail. Overall your work looks impressive. One 
thing I should have mentioned is that contrary to the way it's done right 
now, it's probably not desirable to continue to have one directory per 
plugin. I guess within the next two or three days, I should find a chance to 
review your work, reorganize the file-structure, submit to CVS, and give you 
a CVS account.
Until then, maybe you should keep track of which plugins you modify locally, 
so you'll know where to merge changes, once I'm done.

I'll look at it.

Ah, actually it's not a bug but a questionable feature: Currently the code 
frame only shows the preprocess () and calculate () stages. Probably this 
does not really make too much sense, and I'll change it to show everything.

I see. Well, the reason it's not quite this easy, is because what's displayed 
on the console is not necessarily completely well-formed syntax. In 
particular:
1) there are prompts ("> " and "+ ") at the beginning of lines
2) there are lines of output in between
3) there may have been syntax errors like e.g. misbalanced quotes in earlier 
lines, but those should not affect the syntax-highlighting of subsequent 
lines.
All this means that we can't just use a powerful kate part here, to do 
syntax-highlighting. It may somehow be possible to still make use of kate 
highlighting capabilities somehow, but not in a straightforward way. So I 
think it's too tedious to be a priority right now. You could still add it as 
a wishlist item, however, so it will be reconsidered sometime later, when 
there are fewer excuses to imperfection...

Thomas
