An SXF lattice description is an ascii listing that contains one named, "flat", ordered list of elements, delimited as {...}, with one entry for each element. The list resembles a MAD "sequence" describing the entire machine. The syntax is supposed to be adapted for ease of reading by human beings and for ease of parsing by LEX and YACC.
