You're failing to differentiate between python programmer and a
system's users. I understand packages well enough, but I need to
reduce the users' requirements down to simply running a command. I
don't see a way to do that as of now without a large amount of
boilerplate code in every script.
I've considered installing the thing to the PYTHONPATH as most people
suggest, but this has two drawbacks:
* Extremely hard to push thru my IT department. Possibly impossible.
* Local checkouts of scripts use the main installation, rather than
the local, possibly revised package code. This necessitates the
boilerplate that installation to the PYTHONPATH was supposed to avoid.
* We can work around the previous point by requiring a user-owned
dev installation of Python, but this raises the bar to entry past most
of my co-developers threshold. They are more comfortable with tcsh and
I think the issue here is that the current python-package system works
well enough for the core python devs but leaves normal python
developers without much options beyond "all scripts in one directory"
or "tons of boilerplate everywhere".
