xyling – Draw syn­tac­tic trees, etc., for lin­guis­tics lit­er­a­ture, us­ing xy-pic

The macros in this pack­age model the con­struc­tion of lin­guis­tic tree struc­tures as a gen­uinely graph­i­cal prob­lem: they con­tain two types of ob­jects, BRANCHES and NODE LABELS, and these are po­si­tioned rel­a­tive to a GRID. It is es­sen­tial that each of these three el­e­ments is con­structed in­de­pen­dent of the other two, and hence they can be mod­i­fied with­out un­wanted side ef­fects. The macros are based on the xy-pic pack­age.
