=== Running recipes at the end of a recipe

Dependencies of a recipes always run before a recipe starts. That is to say, the dependee always runs before the depender.

You can call Just recursively to run a recipe after a recipe ends. Given the following justfile:

```make
a:
echo 'A!'

b: a
echo 'B!'
just c

c:
echo 'C!'
```

…running 'b' prints:

```sh
$ just b
echo 'A!'
A!
echo 'B!'
B!
echo 'C!'
C!
```

This has some limitations, since recipe `c` is run with an entirely new invocation of Just: Assignments will be recalculated, dependencies might run twice, and command line arguments will not be propagated to the child Just process.

Recipes that start with a `#!` are executed as scripts, so you can write recipes in other languages:
