xcode7 - How to find out Cocoapods library dependencies? -

when run pod install, seeing libraries installed not specified in podfile. presumably these dependencies of libraries specified. how go finding out library in podfile causes specific library installed?

for example, purelayout not specified in podfile, know what's in podfile causes installed.

analyzing dependencies downloading dependencies installing afnetworking (2.6.3) installing bolts (1.6.0) installing cocoalumberjack (2.2.0) installing purelayout (3.0.1) 

if open podfile.lock file, can see dependencies of pod in pods section:

pods:   - kif (3.3.0):     - kif/core (= 3.3.0)   - kif/core (3.3.0)   - ochamcrest (4.3.0)   - ocmockito (2.0.1):     - ochamcrest (~> 4.0) 

this shows kif requiring kif/core (a "subspec" in cocoapods parlance), , ocmockito requiring ochamcrest (a dependency on separate cocoapod).
