+kelbt (Backtracking LR Parsing)
+
+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.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
