+%description
+ Kelbt generates backtracking LALR(1) parsers. Where traditional
+ LALR(1) parser generators require static resolution of shift/reduce
+ conflicts, Kelbt generates parsers that handle conflicts by
+ backtracking at runtime. Kelbt is able to generate a parser for any
+ context-free grammar that is free of hidden left recursion. Kelbt
+ is different from other backtracking LR systems in two ways. First,
+ it introduces a class of actions called undo actions. These actions
+ are invoked as the backtracker undoes parsing and allow the user
+ to revert any side effects of forward semantic actions. This makes
+ it possible to backtrack over language constructs that must modify
+ global state in preparation for handling context dependencies.
+ Second, Kelbt enables a user-controlled parsing strategy that
+ approximates that of generalized recursive-descent parsing with
+ ordered choice. This makes it easy for the user to resolve language
+ ambiguities by ordering the grammar productions of a non-terminal
+ according to precedence. It is approximate in the sense that for
+ most grammars the equivalent of an ordered choice parsing strategy
+ is achieved. In cases where productions are parsed out of the order
+ given, there is a simple grammar transformation that remedies the
+ problem.
