I have to face the old problem again.
When I transplante SCS back to linux,
glReadPixels take a very long time.
Now, the first project has been upload to SF by svn.
But, there is so many problem during using svn.
The next things to deal with is to upload the document's tex project.
And using autotools to manage the project.
"http://home.ustc.edu.cn/~yukunlin" is no longer used.
SF becomes the new home of SCS.
