@subsection Choosing Files
As shown above, any arguments other than options specify an executable
-file and core file; that is, the first argument encountered with no
-associated option flag is equivalent to a @samp{-se} option, and the
-second, if any, is equivalent to a @samp{-c} option. Many options have
-both long and short forms; both are shown here. The long forms are also
-recognized if you truncate them, so long as enough of the option is
-present to be unambiguous. (If you prefer, you can flag option
-arguments with @samp{+} rather than @samp{-}, though we illustrate the
-more usual convention.)
