Python Script to Export changed Files in a revision range

A friend of mine asked me if subversion has a function to export changed
Files in
a revision range, because she want to send the zipped exported directory to
customer
to overwrite the old version. After googled, I find a Windows BAT(with linux
tools) <http://svn.haxx.se/users/archive-2007-06/0977.shtml> , a
java<http://orangepips.instantspot.com/blog/2008/03/06/Export-Subversion-Files-Changed-between-Two-Revision-Numbers>
and a TortoiseSVN solution. I think the solutions above all have its own
defect, So I
decided to write a cross platform script with python.

The script is here:

I write a simple introduction:
