In addition, the option
.B -singleInstance
is treated like an X option (it must appear before all other
options), and it runs MrEd in single-instance mode.
In single-instance mode, when an existing instance
is running with the same host and executable name, all non-option
arguments are treated as file names and sent to the 
existing instance.
