`src' holds the C code for Emacs (the Emacs Lisp interpreter and its primitives, the redisplay code, and some basic editing functions). While it's true that this gateway is only open to those willing to look at Lisp code (which is often considered old-fashioned), it's an important cultural stance to take, in which you expect that there's an easy and instantaneous avenue to view the source code of what you're using and that the source code is documented and hackable. It can be used to browse any type of file and supports parsing of Java, C, C++, Elisp and some other code like perl, TeX, LaTeX.
