=head1 WebService::Google-Hack Web Interface

=head1 SYNOPSIS

The WebService::Google-Hack web interface provides an easy to use interface
for some of the features of WebService::Google-Hack.

=head1 DESCRIPTION

To install the interface please follow these steps:

1) Create a directory named ghack in your cgi-bin directory (Where all your cgi files reside). So it should be something like:

/webspace/cgi-bin/ghack

2) Next, copy the file named google_hack.cgi, which is given with the 
distribution of the google-hack package into your cgi-bin/ghack/ directory.

3) Open the index.cgi file.

*Note:
The index.cgi file is in the WebInterface directory of GoogleHack.
For eg: WebService/GoogleHack/WebInterface/.

4) Now, in the index.cgi  file (which is also given in the  WebInterface directory of GoogleHack),

Set the remote_host, and remote_port variables to the correct values.

$remote_host = '';

$remote_port = '';

The remote host will be the IP address of the machine where the google_hack server will be running.
The remote port needs to be the same as the $LOCALPORT variable in ghack_server.pl

5) Set the defaultKey variable to your default Google-API key.

    $defaultKey="XXXXXXXXX";

You should now be able to use the web interface.
