// JavaScript function browser_check(version) with ASP support.
// This function determines what browser and version is used. It also decides
// if the used browser is OK to use with Pnet or Picnic.
// To handle differences between Caradoc versions, set argument version to 'Pnet', 'C3', 'Pnet3' or 'Picnic'
// 
// The BrowserDetect object structure is copied from QuirksMode.org. See details below.
//
// Information is stored in the following variables:
//   browserName
//   browserVersion
//   browserStatus
//   osName
//   screenSize

// browserStatus can have the following values:
//   ok      *service* supports your browser.
//   bad     *service* does not support your browser
//   tol     browser works with some problems
//   tol6    browser works with some problems, special for IE 6.
//   tol7    browser works with some problems, special for IE 7.
//   tol9    browser works with some problems, special for IE 9.
//   unknown *service* has not been evaluated with your browser

// @usage  Shall be included in the head section of index.asp or any page where browser version is required.
//         You may set a variable called fakeUserAgent BEFORE loading this file, in order to simulate a different browser
