(description
"@code{re2c} generates minimalistic hard-coded state machine (as opposed
to full-featured table-based lexers). Flexible API allows generated code
to be wired into virtually any environment. Instead of exposing traditional
@code{yylex()} style API, re2c exposes its internals. Be sure to take a look
at examples, they cover a lot of real-world cases and shed some light on dark
corners of re2c API.")
