+     LPegLabel is a conservative extension of the LPeg library that provides
+     an implementation of Parsing Expression Grammars (PEGs) with labeled failures.
+     By using labeled failures we can properly report syntactical errors.
+     We can also recover from such errors by describing a grammar rule with
+     the same name of a given label.
+     LPegLabel also reports the farthest failure position in case of an ordinary failure.
