It is in GenericStockItem.php.

I know it seems like alot, but these things offer alot of functionality 
and part of the point of the print messages is to more easily allow 
uniform error/warn/info/etc. messages. That applies to theme/style 
changes as well, which makes it quite easy when you want to change it.  
More so, as you've realized,  it makes readability and maintenance on 
the code much much easier and simply cuts down on duplicating code. For 
example - if I look at a print/echo, I have to read it to figure out 
what's happening, what it's going to look like, etc - prnErrMsg tells me 
at a glance. With the endWEBERP() - again, painfully obvious what's 
happening - and what if we find later that something else is necessary 
in the 'shutdown' process? In all these case, you get 1 central place to 
change things (or have problems track back to) rather than having to fix 
it every place it was used (and hoping you found them all).
I understand the ease you feel in having all the code in one file, but 
you may want to take a step back and rethink that in some of these 
cases. If you come to the same conclusion, can we at least leave that 
stuff in there for me and anyone else who finds using these things 
helpful? I know I tend to bury stuff, but I usually work real hard on 
making it work well before I do... many developers do things like you've 
seen me do - having it accessible (even if not strictly used) will also 
help some new contributor ramp up quicker. Believe me from having just 
done it - it took alot of work to figure out what was happening in 
places - much of that is necessary - what I've pulled out are things 
that I did not want to have to think about/look at again. Documentation 
of the functions used, almost api docs, is probably needed.
This is also part of the reason I use PHP instead of, say, writing nasty 
C based CGI scripts - many of it's functions/variables cover up things 
that I simply do not need to mess with, but when I do, I still can.
