 Or, for example, for a tab-separated values dump:
-  ./ypp-commodities --tsv >commods.tsv
+   ./ypp-commodities --tsv >commods.tsv
 
 While it is capturing the screenshots, do not move the mouse or use
 the keyboard.  Keyboard focus must stay in the YPP client window.
+If you use Gnome or KDE you must raise the YPP client window so that

+this but metacity and kwin do not honour the request.
