"Laying out GUIs works the same way as building lists with " { $vocab-link "make" }
". Gadgets are layed out using " { $vocab-link "ui.gadgets.tracks" } " through " { $link <hbox> } " and " { $link <vbox> } ", which allow both fixed and percentage widths. "
{ $link , } " and " { $link -> }  " add a model or gadget to the gadget you're building. "
"Also, books can be made with " { $link <book> } ". "
{ $link <spacer> } "s add flexable space between items." $nl
"Using " { $link with-interface } ", one can pre-build templates to add items to later: "
"Like in the StringTemplate framework for java, placeholders are defined using $ PLACERHOLDER-NAME $ "
"Using PLACEHOLDER-NAME again sets it as the current insertion point. "
"For examples using normal layout, see the " { $vocab-link "sudokus" } " demo. "
