flo_scene 0.2.0

//!
//! Runs a minimal subprogram that prints 'hello, world' using the default text output subprogram and then quits
//!
//! We can just specify that we want to send a 'TextOutput' message without needing to know what handles it, so while
//! this will just send to stdout, it's possible to reconfigure the behaviour without changing the subprogram itself
//! say to suppress the output from just one program or process it independently.
//!
