+#### `'static` lifetime elision
+
+[Unstable] Both constant and static declarations of reference types have
+*implicit* `'static` lifetimes unless an explicit lifetime is specified. As
+such, the constant declarations involving `'static` above may be written
+without the lifetimes. Returning to our previous example:
+
+```rust
+# #![feature(static_in_const)]

+const BIT2: u32 = 1 << 1;

+
+Note that if the `static` or `const` items include function or closure
+references, which themselves include references, the compiler will first try the
+standard elision rules ([see discussion in the nomicon][elision-nomicon]). If it
+is unable to resolve the lifetimes by its usual rules, it will default to using
+the `'static` lifetime. By way of example:

+#### Struct field init shorthand
+
+When initializing a data structure (struct, enum, union) with named fields,
+allow writing `fieldname` as a shorthand for `fieldname: fieldname`. This
+allows a compact syntax for initialization, with less duplication.
+
+In the initializer for a `struct` with named fields, a `union` with named
+fields, or an enum variant with named fields, accept an identifier `field` as a
+shorthand for `field: field`.
+
+Example:
+
+```
+# #![feature(field_init_shorthand)]
+# struct Point3d { x: i32, y: i32, z: i32 }
+# let x = 0;
+# let y_value = 0;
+# let z = 0;
+Point3d { x: x, y: y_value, z: z };
+Point3d { x, y: y_value, z };

 //! by two zero-length breaks. The algorithm will try its best to fit it on a
 //! line (which it can't) and so naturally place the content on its own line to
 //! avoid combining it with other lines and making matters even worse.
+//!
+//! # Explanation
+//!
+//! In case you do not have the paper, here is an explanation of what's going
+//! on.
+//!
+//! There is a stream of input tokens flowing through this printer.
+//!
+//! The printer buffers up to 3N tokens inside itself, where N is linewidth.
+//! Yes, linewidth is chars and tokens are multi-char, but in the worst
+//! case every token worth buffering is 1 char long, so it's ok.
+//!
+//! Tokens are String, Break, and Begin/End to delimit blocks.
+//!
+//! Begin tokens can carry an offset, saying "how far to indent when you break
+//! inside here", as well as a flag indicating "consistent" or "inconsistent"
+//! breaking. Consistent breaking means that after the first break, no attempt
+//! will be made to flow subsequent breaks together onto lines. Inconsistent
+//! is the opposite. Inconsistent breaking example would be, say:
+//!
+//! ```
+//! foo(hello, there, good, friends)
+//! ```
+//!
+//! breaking inconsistently to become
+//!
+//! ```
+//! foo(hello, there
+//!     good, friends);
+//! ```
+//!
+//! whereas a consistent breaking would yield:
+//!
+//! ```
+//! foo(hello,
+//!     there
+//!     good,
+//!     friends);
+//! ```
+//!
+//! That is, in the consistent-break blocks we value vertical alignment
+//! more than the ability to cram stuff onto a line. But in all cases if it
+//! can make a block a one-liner, it'll do so.
+//!
+//! Carrying on with high-level logic:
+//!
+//! The buffered tokens go through a ring-buffer, 'tokens'. The 'left' and
+//! 'right' indices denote the active portion of the ring buffer as well as
+//! describing hypothetical points-in-the-infinite-stream at most 3N tokens
+//! apart (i.e. "not wrapped to ring-buffer boundaries"). The paper will switch

-/// In case you do not have the paper, here is an explanation of what's going
-/// on.
-///
-/// There is a stream of input tokens flowing through this printer.
-///
-/// The printer buffers up to 3N tokens inside itself, where N is linewidth.
-/// Yes, linewidth is chars and tokens are multi-char, but in the worst
-/// case every token worth buffering is 1 char long, so it's ok.
-///
-/// Tokens are String, Break, and Begin/End to delimit blocks.
-///
-/// Begin tokens can carry an offset, saying "how far to indent when you break
-/// inside here", as well as a flag indicating "consistent" or "inconsistent"
-/// breaking. Consistent breaking means that after the first break, no attempt
-/// will be made to flow subsequent breaks together onto lines. Inconsistent
-/// is the opposite. Inconsistent breaking example would be, say:
-///
-///  foo(hello, there, good, friends)
-///
-/// breaking inconsistently to become
-///
-///  foo(hello, there
-///      good, friends);
-///
-/// whereas a consistent breaking would yield:
-///
-///  foo(hello,
-///      there
-///      good,
-///      friends);
-///
-/// That is, in the consistent-break blocks we value vertical alignment
-/// more than the ability to cram stuff onto a line. But in all cases if it
-/// can make a block a one-liner, it'll do so.
-///
-/// Carrying on with high-level logic:
-///
-/// The buffered tokens go through a ring-buffer, 'tokens'. The 'left' and
-/// 'right' indices denote the active portion of the ring buffer as well as
-/// describing hypothetical points-in-the-infinite-stream at most 3N tokens
-/// apart (i.e. "not wrapped to ring-buffer boundaries"). The paper will switch
-/// between using 'left' and 'right' terms to denote the wrapped-to-ring-buffer
-/// and point-in-infinite-stream senses freely.
-///
-/// There is a parallel ring buffer, 'size', that holds the calculated size of
-/// each token. Why calculated? Because for Begin/End pairs, the "size"

+/// This is a small server which is intended to run inside of an emulator. This
+/// server pairs with the `qemu-test-client` program in this repository. The
+/// `qemu-test-client` connects to this server over a TCP socket and performs
+/// work such as:
+///
+/// 1. Pushing shared libraries to the server
+/// 2. Running tests through the server
+///
+/// The server supports running tests concurrently and also supports tests
+/// themselves having support libraries. All data over the TCP sockets is in a
+/// basically custom format suiting our needs.
