-%       These definitions for tree macros are taken from "Trees in TeX",
-%       by David Eppstein, as published in TUGboat 6#1, March 1985.
-%       David Eppstein's address (as of 15 June 1988) is
-%               Computer Science Department
-%               Columbia University

-%              Tree -- a macro to make aligned (horizontal) trees in TeX
-%
-%    Input is of the form
-%        \tree
-%           item
-%           \subtree
-%              \leaf{item}
-%                 .
-%                 .
-%                 .
-%           \endsubtree
-%           \subtree
-%              .
-%              .
-%              .
-%           \endsubtree
-%        \endsubtree
-%     \endtree
-%
-%    Nesting is to any level.  \leaf is defined as a subtree of one item:
-% \def\leaf#1{\subtree#1\endsubtree}.
-%
-%    A structure:
-%       \subtree
-%          item_part1
-%          item_part2
-%               .
-%               .
-%               .
-%
-% will print item_part2 directly below item_part1 as a single item
-% as if they were in a \box.
-%
-%    The macro is a 3-pass macro.  On the first pass it sets up a data
-% structure from the \subtree ... \endsubtree definitions.  On the second pass
-% it recursively calculates the width of each level of the tree.  On the third
-% pass it sets up the boxes, glue and rules.
-%

-%
-%             Pass 1
-% At the end of pass 1, the tree is coded as a nested collection of \hboxes
-% and \vboxes.
