As I'm impressed of the overall architecture of CLIM, which is very well
designed, I was surprised of the bad integration of indenting-output and 
filling-output. If these features were put in user-requested add-on's,
thats
an explanation. It was not my intention to critize anything more than this
limited integration and documentation. It just took me the rest of the
night
to get nothing working -- I should not mail having too little sleep...
Please excuse my bad and accusing writing style!

It does't work with CLIM 1.1. Longing for CLIM 2.0 ...

I'll think about that.
