+### Conditional compilation
+
+Sometimes one wants to have different compiler outputs from the same code,
+depending on build target, such as targeted operating system, or to enable
+release builds.
+
+There are two kinds of configuration options, one that is either defined or not
+(`#[cfg(foo)]`), and the other that contains a string that can be checked
+against (`#[cfg(bar = "baz")]` (currently only compiler-defined configuration
+options can have the latter form).
+
+~~~~
+// The function is only included in the build when compiling for OSX
+#[cfg(target_os = "macos")]
+fn macos_only() {
+  // ...
+}
+
+// This function is only included when either foo or bar is defined
+#[cfg(foo)]
+#[cfg(bar)]
+fn needs_foo_or_bar() {
+  // ...
+}
+
+// This function is only included when compiling for a unixish OS with a 32-bit
+// architecture
+#[cfg(unix, target_word_size = "32")]
+fn on_32bit_unix() {
+  // ...
+}
+~~~~
+
+This illustrates some conditional compilation can be achieved using the
+`#[cfg(...)]` attribute. Note that `#[cfg(foo, bar)]` is a condition that needs
+both `foo` and `bar` to be defined while `#[cfg(foo)] #[cfg(bar)]` only needs
+one of `foo` and `bar` to be defined (this resembles in the disjunctive normal
+form). Additionally, one can reverse a condition by enclosing it in a
+`not(...)`, like e. g. `#[cfg(not(target_os = "win32"))]`.
+
+To pass a configuration option which triggers a `#[cfg(identifier)]` one can use
+`rustc --cfg identifier`. In addition to that, the following configurations are
+pre-defined by the compiler:
+
+ * `target_arch = "..."`. Target CPU architecture, such as `"x86"`, `"x86_64"`
+   `"mips"`, or `"arm"`.
+ * `target_endian = "..."`. Endianness of the target CPU, either `"little"` or
+   `"big"`.
+ * `target_family = "..."`. Operating system family of the target, e. g.
+   `"unix"` or `"windows"`. The value of this configuration option is defined as
+   a configuration itself, like `unix` or `windows`.
+ * `target_os = "..."`. Operating system of the target, examples include
+   `"win32"`, `"macos"`, `"linux"`, `"android"` or `"freebsd"`.
+ * `target_word_size = "..."`. Target word size in bits. This is set to `"32"`
+   for 32-bit CPU targets, and likewise set to `"64"` for 64-bit CPU targets.
+ * `test`. Only set in test builds (`rustc --test`).
+ * `unix`. See `target_family`.
+ * `windows`. See `target_family`.
