Well, the verbiage is classical ñu stuff, but I've used both true and
false. In scripts they are not normally needed ( as you can use a
function, or tweak the code ), but there are programs which need to
execute an external thing and dispatch on it's result ( a classical
trick is using it as archive_command in postgres when you do not want
to archive in tests, it tell the server you are done with the current
file ). You have more bizarre ones, like 'yes' ( there is no 'no', you
use 'yes no' for that ).
