Summary description:  Nested delimiter groups extending over multiple array cells or lines

Announcement text:
----------------------------------------------------------------------
 
 The longmath package provides yet another solution to some well known 
 typesetting problems solved in a variety of ways: multi line formulas 
 with paired and nested delimiters. It tackles the problem at the Lua 
 level, which has some advantages over solutions implemented in TeX. 
 In particular, the TeX code need not be executed multiple times, and 
 there is no interference between TeX grouping and the nesting of 
 delimiter groups.

 As a byproduct, delimiters can be scaled in various ways, inner 
 delimiters come in different flavours like relational and binary 
 operators, punctuation symbols etc., and outer delimiters can be 
 selected automatically according to the nesting level. Last but not 
 least, delimiter groups can even extend across several array cells 
 or across the whole document. 

 A special environment is provided as well, which allows multi line
 expressions to be placed inside a displayed equation and make TeX 
 do the line splitting and alignment.
