title: cscope or ctags why choose one over the other?
body: <p>I primarily use vim / gvim as an editor and am looking at using a combination of <a href="http://lxr.linux.no/" rel="noreferrer">lxr (the Linux Cross Reference)</a> and either <a href="http://cscope.sourceforge.net/" rel="noreferrer">cscope</a> or <a href="http://ctags.sourceforge.net/" rel="noreferrer">ctags</a> for exploring the kernel source.  However, I haven't ever used either <a href="http://cscope.sourceforge.net/" rel="noreferrer">cscope</a> or <a href="http://ctags.sourceforge.net/" rel="noreferrer">ctags</a> and would like to hear why one might choose one over the other taking into consideration my use of vim as a primary editor.</p>
