| 32 * This function processes any available updates. As part of that process, it | |

| 35 * Two directories are passed to this function: greDir (where the actual | |
| 36 * binary resides) and appDir (which contains application.ini for XULRunner | |
| 37 * apps). If this is not a XULRunner app then appDir is identical to greDir. | |

| 40 * relaunch the current process. | |
| 41 * | |
| 42 * The appVersion param passed to this function is the current application's | |
| 43 * version and is used to determine if an update's version is older than the | |
| 44 * current application version. | |

| 46 * If you want the update to be processed without restarting, set the restart | |
| 47 * parameter to false. | |
