[Scribus] OT kerning (or tracking) specs.

[John R. Culleton]

I have a customer who has a designer who has specified the setting of certain 
text headings etc. with the terminology:
"kerning 250"
or
 "kerning 40"

I am not familiar with this particular terminology. Neither is my InDesign 
consultant.  It looks like 100 may be normal letter spacing but I am not 
sure. In any case I would call this tracking rather than kerning.  Since it 
isn't TeX and isn't InDesign teminology I assume it is Quark-speak. 

Any Quark folk on list who have seen this kind of specification before?   If 
so can you explain what is desired in the two instances shown above? Are 
these 100th parts of an em or an en?  I hate to look ignorant to my customer 
but my experience is primarily in TeX where fiddling with letter spacing is 
more or less anathema.
