.SH "HOW DOES IT WORK?"
.IX Header "HOW DOES IT WORK?"
\&\f(CW\*(C`native_setup_search\*(C'\fR is called before we do anything.
It initializes our private variables (which all begin with underscores)
and sets up a \s-1URL\s0 to the first results page in \f(CW\*(C`{_next_url}\*(C'\fR.
.PP
\&\f(CW\*(C`native_retrieve_some\*(C'\fR is called (from \f(CW\*(C`WWW::Search::retrieve_some\*(C'\fR)
whenever more hits are needed.  It calls the \s-1LWP\s0 library
to fetch the page specified by \f(CW\*(C`{_next_url}\*(C'\fR.
It parses this page, appending any search hits it finds to 
\&\f(CW\*(C`{cache}\*(C'\fR.  If it finds a ``next'' button in the text,
it sets \f(CW\*(C`{_next_url}\*(C'\fR to point to the page for the next
set of results, otherwise it sets it to undef to indicate we're done.
.SH "AUTHOR and CURRENT VERSION"
.IX Header "AUTHOR and CURRENT VERSION"
\&\f(CW\*(C`WWW::Search::AltaVista::NL\*(C'\fR is written and maintained
by Erik Smit, <zoiah@zoiah.nl>.
.PP
The best place to obtain \f(CW\*(C`WWW::Search::AltaVista::NL\*(C'\fR
is from Martin Thurn's WWW::Search releases on \s-1CPAN.\s0
Because AltaVista sometimes changes its format
in between his releases, sometimes more up-to-date versions
can be found at
\&\fIhttp://www.zoiah.nl/programming/AltaVistaNL/index.html\fR.
