Just $0.02 from a user... I'm primarily an OS-X user these days, but have to do Windows once in a while, and help others do Windows (including as an intro to Python instructor)
Once I discovered setuptools "develop" mode, I never looked bak -- it is simpl;y THE way to develop code, particularly if you are working on a lib you want to use from other projects and/or actively develping utility scripts. I really like that I can add some scripts to setup.py, and use either develop mode or regular old install and get nice commands, and it works the same way on Windows and *nix (with the hood closed0 I did all this for a good while before I even noticed that exe launchers -- it "just worked". In fact, the only time I noticed the launchers was a couple years ago when a beta version of setuptools released a broken version -- very frustration -- it would fire up another command window that would then close when the script was done -- not very helpful for nosetests and the like... When I did discover how it all worked, I did think it was a little weird, but Windows simply hasn't been built for command line stuff, so you do what you have to do. Conclusions: 1) an extra bunch of files is a on-issue for most users -- we just need something that works. 2) the exe launcher is a bit fragile and hard to maintain (and even harder to debug) -- but there are smart people working on this. 3) I'd rather not have to mess with PATHEXT, and I particularly don't want to have to tell my students to do it -- environment variables are a pain, and somehow PATHEXT has been fragile for me (and I don't use Cygwin) I cant help thinking a more elegant solution exists, but maybe not.
