/**

* This function processes any available updates. As part of that process, it
|
|
* may exit the current process and relaunch it at a later time.
|
|
*
|
|
* Two directories are passed to this function: greDir (where the actual
|
|
* binary resides) and appDir (which contains application.ini for XULRunner
|
|
* apps). If this is not a XULRunner app then appDir is identical to greDir.
|
|
*
|
|
* The argc and argv passed to this function should be what is needed to
|
|
* relaunch the current process.
|
|
*
|
|
* The appVersion param passed to this function is the current application's
|
|
* version and is used to determine if an update's version is older than the
|
|
* current application version.
|
|
*
|
|
* If you want the update to be processed without restarting, set the restart
|
|
* parameter to false.
|
|
*
|
|
* This function does not modify appDir.
