[gentoo-proxy-maint] Code evaluations

[james]

I thought these questions were a bit too basic gentoo-dev, so I joined
this list in hopes these questions are more appropriate here.


I find myself browsing a variety of software and sub-components, often
they are comprise of many different languages. So are there
tools that will quickly yield a survey of a given github based
project, as to a rough estimate of the breakdown of the different
component languages? by percentages, lines of code, word-count or
any other metric? (any will do just fine).


Next, I'd like to know if there is a (github) tool (code/syntax/script) 
that can parse the given code modules (components) and just render just 
the comments so I can read them? Language specific solutions are just fine.


These (2) methods would greatly enhance my ability to research new
software, or software not in portage for evaluation. For portage, I just 
read the ebuilds and track things down from there. Ebuilds outside
of portage, such as Gerrit, are more of a challenge so is there a 
systematic-quick method to read those ebuilds without download or 
install of the overlay?


Surely developers have these sorts of tricks and scripts or they
are part of a larger package of tools that I need to read about?
All anecdotal information is greatly appreciated.
