If you look at the old Scribe, it used a markup like in this example:
@hemlock runs in the editor process and interacts with other Lisp processes
called @i[eval servers]. A user's Lisp program normally runs in an eval
server process. The separation between editor and eval server has several
advantages:
@begin[itemize]
The editor is protected from any bad things which may happen while debugging a
Lisp program.
Editing may occur while running a Lisp program.
The eval server may be on a different machine, removing the load from the
editing machine.
Multiple eval servers allow the use of several distinct Lisp environments.
@end[itemize]
To make things italic, you would write @i[some text here]. Longer commands would be like in the itemize example. Each paragraph would be an item in this simple version.
