DOS, UNIX and tabs

[Ben]

Hi,

I have a python script on a unix system that runs fine. I have a python
script on a windows system that runs fine. Both use tabs to indent
sections of the code. I now want to run them on the same system,
actually in the same script by combining bits and pieces. But whatever
I try my windows tabs get converted to spaces when I transfer it to the
unix system and the interpreter complains that the indentation style is
not consistent throughout the file. Short of going through 350 lines of
code and manually replacing spaces with tabs what an I do? I'm thinking
there surely must be a simple solution I have missed here!

Cheers,

Ben
