[Zope] installing CMF 2.4.1

Hi there! I have downloaded windows version of CMF 2.4.1 and used WinZip to unpack it. On the install info page http://cmf.zope.org/download/CMF-1.4.2/INSTALL.txt I read the following: "Note for Windows users: if you are using WinZip to unpack the file, be sure to disable the "TAR file smart CR/LF expansion" option (thanks to Frank McGeough for tracking down this problem!)" Now I wonder what this actually means? Or what I actually am told to do here? Is it something I shoul do in WinZip, or something I should do after I have unzipped the file? Thank you for any kind answers! Have a nice day : ) Børge
