The (nausicaa parser-tools infix) library provides utilities to
convert infix notation expressions to prefix notation expressions; the
library is built upon (nausicaa), (nausicaa parser-tools
silex lexer) and (nausicaa parser-tools lalr lr-driver). The
same functionality is packed in the standalone library (nausicaa
language infix) and available as macro which can convert infix to prefix
notation at expand time.
