==== Justfile and Justfile Directory
- `justfile()` - Retrieves the path of the current justfile.
- `justfile_directory()` - Retrieves the path of the parent directory of the current justfile.
For example, to run a command relative to the location of the current justfile:
```
script:
./{{justfile_directory()}}/scripts/some_script
```
==== Dotenv Integration
`just` will load environment variables from a file named `.env`. This file can be located in the same directory as your justfile or in a parent directory. These variables are environment variables, not `just` variables, and so must be accessed using `$VARIABLE_NAME` in recipes and backticks.
