|
|
% 2006/03/08 -- Protected pict2e loading from possible redefinition of ^.
|

|
% Reported by Alan Munn. Extended documentation.
|

|
|
% everything. Updated documentation.
|
||
|
|
|
||
|
|
% 2005/05/22 -- Added customization hooks and `balanced' branch command,

||
|
|
% fixed final whitespace in \leaf. Many small tweaks.
|
||
|
|
|
||
|
|
% 2005/05/13 -- Reorganized mode selection options, merged variant file
|
||
|
|
% forks.
|
||
|
|
|
||
|
|
% 2005/04/07 -- Removed errant spaces, and arranged for trees to be truly
|
||
|
|
% left-aligned or centered.
|
||
|
|
|
||
|
|
% 2005/02/13 -- Added pgf drawing mode, mode selection support.

||
|
|
|
||
|
|
% 2004/07/05 -- Added a way to manipulate the height of single-child nodes.
|
||
|
|
|
||
|
|
% 2002/11/05 -- Fixed display bug in first branch of 5-branching nodes.
|

|
|
% Reported by Paliath Narendran [dran@cs.albany.edu].
|
||
|
|
|
||
|
|
% 2002/04/17 -- Added provision for ``zero branching'' (empty non-terminals),

|
|
% as suggested by Ronald Greenberg [rig@cs.luc.edu].
|
||
|
|
|
||
|
|
% 2001/09/01 -- Finally made LaTeX2e aware; eepic inclusion is now
|

|
|
% controllable by a package option; massively revised
|
||
|
|
% documentation.
|
||
|
|
|
||
|
|
% 2000/10/24 -- Fixed bug in last revision that broke parsing of \qroof.
|
||
|
|
|
||
|
|
% 2000/9/28 -- Fixed handling of empty labels so that tree lines stay
|
||
|
|
% connected.
|
||
|
|
% -- Small spacing fixes: changed \0, \1 and \2 to \rlap their
|
||
|
