[openbox] pipe menus

[Jorge Almeida]

About pipe menus, to which concept I just started paying attention, I
would like to confirm whether I got the picture: when one such menu is
launched, via a hot key, a certain program "COMMAND" is called, its
output (which should be a syntactically correct xml menu file) is read and
used to display a menu. What if the data the menu was based on change
while the menu is being displayed? Is the menu updated only when
launched?
