will only need to clone once.

directory, you will see that it contains a copy of the project files,
called the <<def_working_tree,working tree>>, together with a special
top-level directory named `.git`, which contains all the information
cloned from, using linkgit:git-remote[1]:

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`,

- 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`,

`BUILT_INS` in the `Makefile`.
