Heh heh. :)


cscope
------

At the top of your source tree `make cscope.out`.

In emacs, while in a .c or .h file, while point is on a function, try «C-c s
g» to invoke cscope-find-global-definition, to jump to the thing's
implementation.

While in a function «C-c s c» to invoke
cscope-find-functions-calling-this-function, which is pretty useful.


emacs code browser
------------------

I don't use it all that often, but the emacs code browser
<http://ecb.sourceforge.net/> is pretty nifty.  «M-x ecb-activate» will get
it active in a buffer, then «C-c . l w» will toggle the navigation pane,
showing a tree of everything (includes, typedefs, local variables, function
signatures, classes, &c.) defined in the file.  «C-c . g m» will goto this
"method" pane for selection/naviagation.  I'm sure that's just the surface of
ECB, which I really should learn in depth.  One of the nice things about ECB
is that it supports multiple languages … C, scheme, elisp, python, java …
