      (description "Clojure is a dynamic, general-purpose programming language,
combining the approachability and interactive development of a scripting
language with an efficient and robust infrastructure for multithreaded
programming.  Clojure is a compiled language, yet remains completely dynamic
– every feature supported by Clojure is supported at runtime.  Clojure
provides easy access to the Java frameworks, with optional type hints and type
inference, to ensure that calls to Java can avoid reflection.

Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy
and a powerful macro system.  Clojure is predominantly a functional programming
language, and features a rich set of immutable, persistent data structures.
When mutable state is needed, Clojure offers a software transactional memory
system and reactive Agent system that ensure clean, correct, multithreaded
designs.")

tree for that string.

@item @dfn{No Grammar Left Behind}: Works for @emph{any} context-free grammar,
including @emph{left-recursive}, @emph{right-recursive}, and @emph{ambiguous}
grammars.

@item Extends the power of context-free grammars with PEG-like syntax for
lookahead and negative lookahead.

@item Supports both of Clojure's most popular tree formats (hiccup and enlive)
as output targets

@item Detailed reporting of parse errors.

@item Optionally produces lazy sequence of all parses (especially useful for
diagnosing and debugging ambiguous grammars).

@item ``Total parsing'' mode where leftover string is embedded in the parse
tree.

@item Optional combinator library for building grammars programmatically.

@item Performant.
