Rees. +% +% This work consists of all files listed in manifest.txt. + +This package supports drawing proof trees of the kind often used in +introductory logic classes, especially those aimed at students without strong +mathemtical backgrounds. Hodges (1991) is one example of a text which uses +this system. When teaching such a system it is especially useful to annotate +the tree with line numbers, justifications and explanations of branch +closures. + +prooftrees provides a single environment, prooftree, and a variety of tools +for annotating, customising and highlighting such trees. A cross-referencing +system is provided for trees which cite line numbers in justifications for +proof lines or branch closures. + +prooftrees is based on Forest and, hence, TikZ. The package requires version +2.0.3 of Forest for expected results and will not work with version 1. + +The author is certain that some of her beliefs are false, but sure that her +belief that prooftrees has bugs is not among them. + +Clea F.
