Meaning

In general the print_usage method should not be used from the end-user because it is already safely (and automatically) used by the library. However, for taking into account very peculiar circumstances, it is publicly exposed.

use flap
...
type(command_line_interface):: cli

call cli%init(...)
call cli%add(...)
