Hi,

We're working on upgrading an older piece of software where the scanning
and parsing was done using hand-written codes and has encountered many
problems over the years. We're looking at tools to migrate towards and the
Spirit lexer and parser tools are possibilities. Also this will be a staged
migration--we can't do everything at once. Right now we're only interested
in Spirit lex.

Question: Can the lexer access/retrieve the actual string token during
scanning. For example, Flex can do this using the yytext() function. The
examples I've seen on the web including the Boost site do not illustrate
how this can be done using just Spirit lex.

Thanks,
Brian
