A new package has been installed on tug.ctan.org and should have by now made its way to your favorite local mirror.
Thanks for the upload, Jim Hefferon
======================================================================
The following information was provided by the package's contributor.
Name of contribution: egameps Author's name: Martin J. Osborne Location on CTAN: macros/latex/contrib/egameps Summary description: LaTeX style for typesetting extensive games, using PSTricks macros License type: lppl
Announcement text given by the package's contributor: - ---------------------------------------------------------------------- The style is intended to have enough features to draw any extensive game with relative ease. (An older version, which uses the LaTeX picture environment rather than the PSTricks macros (and consequently has many fewer features), is available on my website.) - ----------------------------------------------------------------------
You can have a look at the package at http://tug.ctan.org/tex-archive/macros/latex/contrib/egameps although you may get a better network connection by visiting a mirror of CTAN that is near to you; see http://www.ctan.org/tex-archive/README.mirrors
