Summary: translate Windows cr-lf when installing scripts on Linux
Initial Comment:
PROBLEM
If a file installed as a script has Window cr-lf
endings, even if the '#!/usr/bin/env python' is
included to support direct execution on Linux, it
doesn't work because the shell is confused by the
cr-lf.
This problem has been addressed in the newsgroups,
with the usual solution to manually change the line
endings, or only develop with an editor that can
maintain Linux line endings.
SOLUTION
Convert line endings on installed scripts to the line
endings appropriate to the machine running the
installation. Could be limited to Unix/Linux
platform because Windows doesn't care about the line
endings.
kindest regards,
tim

I put this back in distutils category instead of Python core. I read over
what I had written (and the response from kbk) and it is obvious that I
wasn't clear.
A Windows developer that uses distutils would be frustrated by their
scripts not working on Unix/Linux because of the cr-lf endings, even if
they had included the Unix/Linux '#!/usr/bin/env python' as the first
line.
I am asking that when _distutils_ installs an executable script that the
line endings in each executable script are set to those appropriate for
the target machine.
In this way a Windows programer can ignore the line-ending formats of
their scripts and distutils will quietly take care of the problem.
sorry for the confusion and I hope that I have explained my idea
better.

See PEP 278, implemented at Python 2.3.
It is better not to automagically modify the script
when running it. However, there is a script
'crlf.py' in Tools/scripts which will convert
files with Windows line endings to Unix
line endings, if you wish to do that.
