//  ------------------------------

//
//  ------------------------------
//	io_contentURL - (string)
//  NOT USED by the Adobe Labs Library mode
//  This parameter is used by ADEBadgeLauncher.js
//
//  How the ADE Launcher SWF handles this parameter is based on
//  the setting of io_doFulfillmentLink.
//
//  If io_doFulfillmentLink is false, then io_contentURL is
//  intended to be a URL path to an un-encrypted ePub or PDF Document.
//  io_contentURL will be sent to DE by the Launcher SWF and then
//  DE will download the file, add to the DE library, and open for reading
//
//  If io_doFulfillmentLink is true, then io_contentURL is
//  intended to be a GBLink fulfillment URL for Adobe Content Server DRM fulfillment
//  The launcher SWF will play the io_contentURL into the browser frame to
//  simulate a user clicking a GBLink URL href on a HTML page.  The target
//  ACS server will respond in the normal way with the ETD mime response to
//  be handed to DE by the browser.  DE will handle the ETD response as usual and
//  fulfill the ACS DRM protected content.
//
//  VERY IMPORTANT:
//  The io_contentURL must be escaped (js escape() function) to retain its integrity
//
//  USE fix_gblink_plus_characters() with ACS GBLink URL
//  There is a helper function named fix_gblink_plus_characters() in the ADE Launcher SDK
//  that is provided to perform the final fix for io_contentURL that is used with
//  io_doFulfillmentLink = true for GBLink URLs.  Please read the documentation and example
//  at fix_gblink_plus_characters() and in the ADE Launcher SDK examples
//
//  NOTE: When io_sendButtonPush is true, then even if io_contentURL is set, it will not
//  be sent to ADE after it is launched.  When io_sendButtonPush is true, all that happens
//  after ADE is launched is that the JS Callback is made, and that is it.
//
//  ------------------------------
//	io_autoInstall - (true, false)
//  true - If DE is not installed then install it. When installation of DE starts,
//  the the Adobe EULA always appears.  The user must click through the EULA to complete the install.
//  false - Take no special action to install DE
//
//  ------------------------------
//	io_autoLaunch - (true, false)
//  true - If DE is installed then launch it.  If DE not installed, do nothing special
//  false - Take no special action to launch DE
//
//  ------------------------------
//  io_MMredirectURL - (string)
//  This is a URL that is used if NO Flash Version is detected or the Flash Version
//  is too low to run the Launcher SWF.
//  This URL should go to a warning page that is maintained by the
//  partner that says something like
//
//  Can't see this content? To view this content, JavaScript must be enabled,
//  and you need the latest version of the Adobe Flash Player. Download the Flash Player now!
//
//  www.adobe.com/go/getflashplayer is the Adobe GO URL to provide a link for FlashPlayer
//
//  ------------------------------
//  io_doFulfillmentLink - (true, false)
//  true - submit "io_contentURL" parameter into browser (for ACS GBLink DRM fulfillment URL)
//  false - pass "io_contentURL" through LocalConnection into DE. DE will download the
//  content from the URL, add to the library, and then and open into reading mode
//
//  ------------------------------
//  io_sendADEInstalled - (true, false)
//  true - SWF performs call back into Jscript function setG_nADEInstalled() to indicate
//  installed state of DE.
//  false - DO NOT perform any JScript callback
//
//  ------------------------------
//  io_sendSWFVersion - (true, false)
//  true - SWF performs call back into Jscript function setG_strSWFVersion() to indicate
//  Version of the Adobe Digital Editions Launcher SWF
//  false - DO NOT perform any JScript callback
//
//  ------------------------------
//  io_sendButtonPush - (true, false)
//  true - SWF performs call back into Jscript function send_ADE_SWF_ButtonPush() to indicate
//  ADE is installed and the Button on the SWF is pushed
//  false - DO NOT perform any JScript callback
//
//  NOTE: When io_sendButtonPush is true, then even if io_contentURL is set, it will not
//  be sent to ADE after it is launched.  When io_sendButtonPush is true, all that happens
//  after ADE is launched is that the JS Callback is made, and that is it.
