True. My Bad. I simply had no recollection of the official installation instructions and somehow assumed they were extremely verbose (or something - I dunno really :-) ) and just wanted to provide my non-verbose personal notes (something I do for everything I install and/or configure, unless I know I will be able to remember every little detail of it years from now). It has saved me countless hours through the years...

Ah, bummer. Would it be worth including (in your courier-pythonfilter sources) whatever latest version you (or me or anybody else) have downloaded at some point?
