TreeButton GUI for Trees Put treebutton.py and treerunner.ico in the same folder as trees.py. The icon only works in Windoze. Requires Python 2.4 with Tkinter and Tix installed. These are now nominally standard parts of a Python distribution, but don't always appear in all Linux distros as of March 2006. E.g. Tix seems to be broken in Ubuntu 5.10, and absent from the default install of SUSE 10.0 (but present if you select all the geek stuff). I had success with ActiveState python 2.4.10 on Ubuntu (installed GNU readline5.1 prior to that; dunno if that was essential) Freestanding Windows executables with installer may be found at: http://arts.anu.edu.au/Linguistics/People/AveryAndrews/Software/latex TreeButton can be made to interact reasonably well with the TeXnicCenter front-end for (La)TeX by changing the "%Wm" at the end of the command line specifications in the output profiles to "%bm" (base-name without extension of file being edited). Then you can have the .txp file loaded in the TXC window, push the TreeButton button to run Trees, and then build as usual in TXC.
