    //
    //1. System Requirements
    // Any system which has PHP and a Web server installed.
    // ftp server on the system from where the page is opened and has to be uploaded.
    // Test Broweres - IE, Mozilla
    //

    // i) Untar Wedit.tar.gz
    // ii) Copy Wedit directory into /var/www/html (DocumentRoot directory of the Web Server).
    // iii) File thats opened should have 777 permission
    // iv) set "magic_quotes_gpc = off;" in php.ini and restart Web server
    //
