Description: smdev.js is a compilation of several javascript
funtions to provide a centralized environment with all the common
routines needed for website operation. It includes browser
detection, css loading, alternate text, popup windows,
email validation.

Some of the code included here was coded by other authors and
is so specified where needed.

** DETECT.JS - JS Browser/Version/Platform Detection Library
** =========================================================
** This library contains functions to detect/return the user's
** browser, version, and platform and to jump to a URL if
** the user is using a specified browser and/or version and/or
** platform. It's yours for free; please maintain this header!
**
** To load this library in an HTML doc, put the following

** Functions
** =========
** getBrowser()
**   returns browser: "netscape", "ie", "other"
** getBrowserVer()
**   returns browser version number or "n/a"
** getPlatform()
**   returns browser OS: "mac", "win", "unix", "other"
** ifBVPjump(browser, version, platform, URL);
**   jumps to URL if user's browser, version, platform all
**   match the first three arguments
**   browser - "netscape", "ie", "other", "any"
**   version - "#.x", "#.#[#]", "any"
**             "#.x" matches any version #
**               ex: "4.x" matches 4.0, 4.05, 4.5, etc.
**             "#.#[#]" matches only version #.#[#]
**               ex: "4.05" matches 4.05, not 4.0, 4.5
**   platform - "mac", "win", "unix", "other", "any"
**   URL - relative or absolute URL
**   examples:
**     ifBVPjump("ie", "4.x", "win", "ie4winpage.html");
**       would jump to ie4winpage.html if the user's BVP
**       were IE, 4.x, Windows
**     ifBVPjump("IE", "4.x", "win", "ie4winpage.html");
**       wouldn't work because "ie" is case-sensitive
**    ifBVPjump("any", "any", "unix", "unixpage.html");
**       would jump to unixpage.html if user's P were UNIX
**     ifBVPjump("any", "any", "any", "index.html");
**       would jump to index.html regardless of user's BVP
** isNetscape()
**   returns true if Netscape, false if not
** isIE()
**   returns true if IE, false if not
** isVer3()
**   returns true if version is 3.x, false if not
** isVer4()
**   returns true if version is 4.x, false if not
** isVer4up()
**   returns true if version is 4.0+, false if not
**   this is a quick way to test for DHTML capability
** isVer5()
**   returns true if version is 5.x, false if not
** isMac()
**   returns true if OS is Mac, false if not
** isWin()
**   returns true if OS is Windows, false if not
** isUNIX()
**   returns true if OS is UNIX, false if not
