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.
