I'm having trouble figuring out how to scan the PCI bus the way the pci program does, so I thought I'd try download 
source code.

The website suggests you can view the source code anonymously from the web, but this just sent me round and round in 
circles.

Apparently the only way to do it is via svn.   I typed in the svn command below:

svn checkout --username maschoen@pobox.com http://community.qnx.com/svn/repos/coreos_pub/trunk

I get asked for my password but I always get this message:

Authentication realm: <http://community.qnx.com:80>; Authorization Realm

followed by more requests for my user-id and password.
