Nowadays, `git log` is a builtin, which means that it is _contained_ in the
command `git`. The source side of a builtin is
-- a function called `cmd_<bla>`, typically defined in `builtin-<bla>.c`,
- and declared in `builtin.h`,
+- a function called `cmd_<bla>`, typically defined in `builtin/<bla.c>`
+ (note that older versions of Git used to have it in `builtin-<bla>.c`

- an entry in the `commands[]` array in `git.c`, and
- an entry in `BUILTIN_OBJECTS` in the `Makefile`.
Sometimes, more than one builtin is contained in one source file. For
-example, `cmd_whatchanged()` and `cmd_log()` both reside in `builtin-log.c`,
+example, `cmd_whatchanged()` and `cmd_log()` both reside in `builtin/log.c`,
since they share quite a bit of code. In that case, the commands which are
_not_ named like the `.c` file in which they live have to be listed in
`BUILT_INS` in the `Makefile`.
