In the case your command-line has a remainder (that is, a non-options
part; see Option Separator in The Clon End-User Manual and Synopsis Items), you
may need to access it in order to process it independently from Clon.
Since Clon is responsible for parsing the command-line, it is also in
charge of figuring out where the remainder of the command-line begins.
The command-line remainder is known to Clon as soon as a context is
created. You can retrieve it by using the remainder function like
this: (remainder). The remainder is provided as a list of strings.
