Arguments

• which: A character vector specifying which types of SSH clients to search for. If NULL, a default set of clients supported by the current platform is searched for.
• first: If TRUE, the first client found is returned, otherwise all located clients are returned.
• must_work: If TRUE and no clients was found, then an error is produced, otherwise only a warning.

The pathnames may be followed by zero or more command-line options, i.e. the elements of the returned list are character vectors of length one or more.
