+
+@itemize
+@item Turns @emph{standard EBNF or ABNF notation} for context-free grammars
+into an executable parser that takes a string as an input and produces a parse
+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.
