This is a rather tricky area.  Some things will break over pages, others
will not.  The most reliable way is to use the existing display and list
item symbols, which do break across pages.  The whole thing looks like a
tagged list to me, so I would be writing

    @TaggedList gap { 0v }

    @TI { "{{" } { paragraphs of text }

    @TI { "}}" } {}

    @EndList

It might need some fiddling with.  If you want to make the Lout source
look nicer it will get harder, although you could try

    import @BasicSetup
    macro @BraceList { @TaggedList gap { 0v } @TI { "{{" } }

    import @BasicSetup
    macro  { @TI { "}}" } {} @EndList }

and thus write

    @BraceList {
    paragraphs of text
    } @EndBraceList

If you want to make it look really nice it's going to have to be a
new kind of display symbol, placed alongside the other display
symbols in the $LOUTLIB/include/bsf file.

Barrie, if you are using 3.24 and you can make a small complete example
document that does this, please send it along.
