address@hidden
address@hidden 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.
+
address@hidden @dfn{No Grammar Left Behind}: Works for @emph{any} context-free 
grammar,
+including @emph{left-recursive}, @emph{right-recursive}, and @emph{ambiguous}
+grammars.
+
address@hidden Extends the power of context-free grammars with PEG-like syntax 
for
+lookahead and negative lookahead.
+
address@hidden Supports both of Clojure's most popular tree formats (hiccup and 
enlive)
+as output targets
+
address@hidden Detailed reporting of parse errors.
+
address@hidden Optionally produces lazy sequence of all parses (especially 
useful for
+diagnosing and debugging ambiguous grammars).
+
address@hidden ``Total parsing'' mode where leftover string is embedded in the 
parse
+tree.
+
address@hidden Optional combinator library for building grammars 
programmatically.
+
address@hidden Performant.
