cscope - download and install

I found it today, hope it can help me browse the helix sdk code. To download and install it is super easy, especially with a linux system. As a developer, using cvs seems is very basic. Here is the way:

cvs -d:pserver:anonymous@cscope.cvs.sourceforge.net:/cvsroot/cscope login
(it prompts for password, just hit enter)

cvs -z3 -d:pserver:anonymous@cscope.cvs.sourceforge.net:/cvsroot/cscope co cscope
(note, my current directory is /home/build/src)

After that what to do, I just eye through INSTALL , then type the following commands:

./configure
make
make install

So cscope is ready to use! and What is the benifit with it? I think that's my next post.
