WWI makes your PHP/CGI website into Windows client-side software by integrating "WebServer + IE Browser + PHP 4.x + CGI" into one simple application.
That means: you can put your PHP/CGI code into WWI, and users can execute your PHP/CGI application through WWI's embeded IE browser without knowing how to install and setup WebServer, PHP, and/or ODBC.
Therefore, It'll be very easy for you to distribute your PHP/CGI-based application.
Provide embeded IE browser to run your PHP/CGI-based application.
Provide ConfigTool software to combine your code with WWI easily.
Provide Customized Interface (ToolBar/SplashScreen/Icon/...).
Provide ODBC setup automatically.
The evaulation version of Win32-Web Integrator for PHP/CGI (WWI) can be used for non-commercial software freely.
You can also distribute the original version of WWI without making profit from it.
But you can't distribute parts of it, or even modify it.
