This tangential topic came up recently because of our recent GothPy (local 
Gothenburg, Sweden Python User's Group) meeting.

One of the members develops TextTest
  http://texttest.carmen.se/index.php?page=main

It is a command-line application with both GUI and non-GUI modes. The GUI uses 
Gtk.

He does not distribute it with setup.py . The installation instructions are 
"call $texttest/bin/texttest.py" or set your path to include the right 
directory.

This causes a problem with me because my system Python is not configured for 
PyGtk. I have a Mac. I used Macports to install PyGtk and use the Python in 
/opt/local/bin/python2.6 . I ended up putting that path in by-hand. I would 
rather have had the normal setup.py script installation program take care of 
that for me.


However, he does not want to install it as a package because the code is not 
designed as a library, and he doesn't want to "pollute" site-packages either 
with this application code.

I said it was okay, and that people write command-line programs like this

#!/usr/bin/env python

import application_package
application_package.main()


I thought that was common practice, and I don't see it as pollution. But now I 
see my views aren't as much in the majority as I thought they were.

What should the practice be? Put this into 
"/usr/local/lib/application_package-$version/ and have the command-line program 
look more like

#!/usr/bin/env python

import sys
sys.path.insert(0, "/usr/local/lib/application-package-$version")
import application_package
application_package.main()

?
