- *
- * This component handles the startup command line argument of the form:

- * by making the current executable the "default mail client."
- *
- * The module is registered under the contractid
- * "@mozilla.org/commandlinehandler/general-startup;1?type=setDefaultMail"

- * The implementation consists of a JavaScript "class" named nsSetDefaultMail,
- * comprised of:
- * - a JS constructor function
- * - a prototype providing all the interface methods and implementation stuff
- *
- * In addition, this file implements an nsIModule object that registers the
