Pear with CI

[eluser]searain[/eluser]
Do you use pear with CI?

The advantages (the for) and disadvantages (the against) using pear with CI?

If you don't use pear with CI, what alternatives you will use? and why?

Pear + CI is good for what kind projects and the alternative is good for what kind projects?

I am recently switching to CI, just try to get everything right as much as I can in the beginning, including select and set up the right tools (extensions, libraries) etc.

Thanks!
