Shebang line on Windows?

[Sells, Fred]

When moving from windows to unix you need to run "dos2unix"   on any programs that use shebang (at least with python 2.6)   that is installed on some platforms but must be installed on others like CentOs but it is in their repository.

A word of warning unless this has since been resolved: Whenever I have tried adding the shebang line on Windows and running it on Unix the latter has complained about the carriage return at the end of the line. This means that Unix does not work when invoked as follows.
(And, yes, the file has had chmod +x applied.)

  ./program.py

It is, of course, OK when run as

  python program.py

but that removes some of the benefit of the shebang line.
