In Judoscript (check that one out, it’s very powerful, yet easy to grab) you can use here-docs. Unix-adepts will know them, since most shell have them too:
cat <
In Judoscript you use [[* as start of a here-doc section and you end it with *]]. Not as flexible as you would like, yes? Since: how can you embed the actual here-doc tags when explaining something? Well, if it's only for display, why not add a non-visible tag like [</>[*. Simple, but effective.
