Help with generating textual output that includes ANSI escape codes for formatting.

Utilities for formatting binary data (byte arrays) or binary deltas.

Utilities for accessing text on the system clipboard using AWT.

This is segregated from other code to prevent the AWT stack from initializing
unnecessarily. On OS X, this initialization is seen as a Java application icon appearing in the Dock.

Assistance for formatting data into columns. Each column has a width, and data within the column
may be left or right justified. Generally, columns are sized to the largest item in the column.
When a value is provided in a column, it may be associated with an explicit width which is helpful
when the value contains non-printing characters (such as those defined in the `io.aviso.ansi` namespace).

Changes exception output for SystemMap and Lifecycle, from
[Stuart Sierra's Component library](https://github.com/stuartsierra/component), to be shorter placeholders.

SystemMap instances print as `#<SystemMap>`.

Lifecycle instances print as `#<Component CLASS>` (where `CLASS` is name of the record class).

Without these changes, exception output for system maps produces volumes of deeply nested
and redundant data.

Format and present exceptions in a pretty (structured, formatted) way.

A plugin for Leiningen that automatically enables pretty printing.

Provides functions that hook into clojure.tools.logging to make use of Pretty to format exceptions.

You must [add clojure.tools.logging as an explicit dependency](https://github.com/clojure/tools.logging) of your project.

Utilities to assist with REPL-oriented development.

If you are using Stuart Sierra's component library, you may want to also require
[[io.aviso.component]].
