Where as with 'scripts' you need to use #!/usr/bin/env python -- which requires that the user's environment conform to the application (e.g. on some terminals on my computer this might point to a Python 3 install, and on another terminal it's supporting an old Python 2.3 based app). It also requires that you install the library files into a specific Python's site-packages, and that also has downsides.

Also consider providing an installer for your application instead. It may be overkill for command-line app with only a couple files which the user needs to customize ... but distutils and setuptools are focused on just managing Python packagaes. If you want to install a python-based application it's nice to have a proper installer. Buildout makes a nice cross-platform install tool - although again that maybe overkill, and you could have a simple 'install-pitz-instance.py' script or such that handles copying the files into a user-editable location.

Also, using entry points is more preferable than using the distutils 'scripts' metadata. The advantage of entry points is that you can write-out the script at install time such that it has a shebang that is hard-coded to a particular Python install and location of the pitz package files. Where as with 'scripts' you need to use #!/usr/bin/env python -- which requires that the user's environment conform to the application (e.g. on some terminals on my computer this might point to a Python 3 install, and on another terminal it's supporting an old Python 2.3 based app).

is installing in "pitz-0.1dev-py2.6.egg" as oposed to just "pitz" the default??

I thought only easy_install does it like that?

pip.py OTOH shouldn't do it.

OK, now I think I get it. To pull the stuff out, I gotta use pkg_resources. Then that library finds the data, regardless of where it might be.

Thanks for the help.

This is the way I have done it in the past: http://peak.telecommunity.com/...

Thanks for the help. I started this task by reading those docs. My problem is that the files that I describe in data_files get installed to a bizarre place:

$ cd ~/virtualenvs/scratch/lib/
$ find -type f -name '*.sample'
./python2.6/site-packages/pitz-0.1dev-py2.6.egg/share/pitz/tracpitz.py.sample
./python2.6/site-packages/pitz-0.1dev-py2.6.egg/share/pitz/agilepitz.py.sample

So it isn't clear how I can find those files from a script later. pitz-0.1dev is not likely to be a fixed location. And same with py2.6.egg.
