+takes a list of filenames and directories on the command-line
+and displays them in a menu for the user to select one.

+the directory contents are displayed as a fresh menu.
+Once the user has selected a filename,
+its absolute path is printed to standard output.

+.Nm vis-open

+as its user-interface,
+so see that page for more details.

+.It Fl -
+If this token is encountered before the first non-option argument,
+all following arguments will be treated as menu-items,

+or after a previous instance of
