Lesson: use *.tar.gz but *.zip under Unix
Today I want to reinstall my subversion client in my Linux box to enable SSL support, so I go to www.tigris.org and download subversion again, but unfortunately I download a zip file, then I fall into a well, the configure script complain can't create makefile correctly for me, after spending 2 hours on debugging, I find the reason is ^M in some important files

After downloading a tar.gz file, all works fine for me now ;)

So even Unix support *.zip and *.tar.gz, but it'd be better to use *.tar.gz but *.zip, otherwise you may meet strange error like me.
