+//! phetch is a terminal Gopher client designed to help you quickly
+//! navigate the Gophersphere securely. It includes support for
+//! browsing via TLS or Tor proxy, but can also be used the old
+//! fashioned way. The menu-based interface is driven entirely by your
+//! keyboard, and emphasis has been put on swiftness of navigation.
+//! Both "jump to link" and incremental search options are available.
+//!
+//! We don't use any ncurses-style library for drawing but instead do
+//! it manually, mainly in `UI`. This is the application class that
+//! prints to the screen and manages the loaded Gopher "views".
+//! Meanwhile, the bulk of the menu system, responding to user
+//! input, and rendering of the colored interface itself takes place
+//! in the `Menu` view. The two work hand-in-hand.
+//!
+//! This crate includes its own Gopher parsing and fetching library,
+//! which may eventually get extracted. It seems that most existing
+//! Gopher libraries in Rust allow you to parse menu lines
+//! individually into items, but phetch needs to know about the links'
+//! relationships to each other for its navigation/numbering/cursor
+//! system to work. So phetch parses all the lines in a Menu as a
+//! whole and knows which link is which.
+//!
+//! Finally, a note on the code itself: this is not my first Rust
+//! program, but you probably wouldn't know that by looking at it!
+//! Suggestions and improvements are more than welcome.
