### Standard arguments
For any formula using a well-known build system, there'll be arguments that should be passed during compilation such that its build conforms to Homebrew standards. These have been collected into a set of `std_*_args` methods (like [`std_configure_args`](https://rubydoc.brew.sh/Formula#std_configure_args-instance_method) and [`std_cmake_args`](https://rubydoc.brew.sh/Formula#std_cmake_args-instance_method) as seen in the [output of `brew create`](#grab-the-url)) that set the build type and installation paths, plus any other applicable options.
Most of these methods accept parameters to customize their output. For example, to set the install prefix to [**`libexec`**](#variables-for-directory-locations) for `configure` or `cmake`:
```ruby
system "./configure", *std_configure_args(prefix: libexec)
system "cmake", "-S", ".", "-B", "build", *std_cmake_args(install_prefix: libexec)
```
### `bin.install "foo"` ### `bin.install "foo"`
You’ll see stuff like this in some formulae. This moves the file `foo` into the formula’s `bin` directory (`/usr/local/Cellar/pkg/0.1/bin`) and makes it executable (`chmod 0555 foo`).
