Announcement text: 
----------------------------------------------------------------------
This package provides macros to produce the "Box notation" of SDRT (and 
DRT, by the way), to draw trees representing discourse relations, and 
finally to have an easy access to various math symbols used in that 
theory, mostly with automatic math mode, so they work the same in 
formulae and in text.
