Some of the code to html conversion tools create alphabetical
lists of functions and such like, as well as calling trees (no
idea how they do recursion), I think GNU do one such tool.

On small projects I just use grep, although I ought to alias a
command like the one in the "info find" that uses xarg to invoke
grep more efficiently.

"find . -name '*.[ch]' | xargs grep -l thing "     

I expect Emacs does it for you somehow as well ;)

Is the Linux kernel a large collection of code? I think the
kernel is medium sized, now KDE is probably getting to the large
size depending how many apps you count as KDE....
