I was a little surprised easy_install didn't already have a "redo the
console scripts" command.
Eggs omit the console scripts and put the normal scripts in
.egg-info/scripts/. If the egg is installed instead of simply added to
sys.path and used then easy_install iterates over the console_scripts
and gui_scripts and writes them out.
Obviously this operation should happen at or near the same time as the
install but it will be quite harmless to append a few lines to RECORD.
Shouldn't be any worse than the #! rewriting that already happens.
I've decided to delay this version of wheel until I can come up with a
patch to pip.
And if you're in a hurry and deploying a web backend, why bother to
generate the scripts at all? (not the default)

It's been a useful way to structure things.
