vim.  But remember, this first one started out as a copy/paste from the 
firefox-7.0.1 screen.

I have no tabs left in the operative code, the python interpreter was 
having a cow if even one was in that last 30-35 lines of code.

Indented the same as the rootdir statement itself, which in python would 
seem to make it immediately sequential to the roodir = statement.

I am gene, running as gene, what could be wrong with giving it /home/gene 
as the argument?

I have another dir in /home/amanda, that I build the alpha and beta amanda 
stuff in.  Let me try that.  And again, this works but I forgot about the 
.ccache directory, so it will take a while to finish.

Now, as a python lesson to me, I will do a blink compare between the 2 
files this evening & see what I munged.  ATM, I am working on a gunstock 
for as long as my feet and back can stand the standing, so sitting here is 
a 'break' from that.  Yeah, I occasionally call myself a JOAT. ;-)

Thanks Dave.

Cheers, Gene
