/**
 * Handles arguments on the command line of an XUL application.
 *
 * Each handler is registered in the category "command-line-handler".
 * The entries in this category are read in alphabetical order, and each
 * category value is treated as a service contractid implementing this
 * interface.
 *
 * By convention, handler with ordinary priority should begin with "m".
 *
 * Example:
 * Category             Entry          Value
 * command-line-handler b-jsdebug      @mozilla.org/venkman/clh;1
 * command-line-handler c-extensions   @mozilla.org/extension-manager/clh;1
 * command-line-hanlder m-edit         @mozilla.org/composer/clh;1
 * command-line-handler m-irc          @mozilla.org/chatzilla/clh;1
 * command-line-handler y-final        @mozilla.org/browser/clh-final;1
 *
 * @status UNDER_REVIEW This interface is intended to be frozen, but it isn't
 *                      frozen yet. Be careful!
 * @note What do we do about localizing helpInfo? Do we make each handler do it,
 *       or provide a generic solution of some sort? Don't freeze this interface
 *       without thinking about this!
