It prints the usage. That is the short help summary. GOption naturally does not 
detect if e.g. an argument is not valid. In the case the application could call 
g_option_context_print_usage(ctx);
and below print the error ("valid range for timeout is 10...20");

The g_option_context_print_usage(ctx); could determine the comman dline template 
from the given GOptionEntries and list tha usage in the form:
myapp <required options> ...
