description="
A fast lexer generator for C and C++.

re2c is a free and open-source lexer generator for C and C++.  Its main
goal is generating fast lexers: at least as fast as their reasonably
optimized hand-coded counterparts.  Instead of using traditional
table-driven approach, re2c encodes the generated finite state automata
directly in the form of conditional jumps and comparisons.
