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.
