We are not aware of the existance of Irix systems in the department of Mathematics and Computer Science. However, we expect the installation to be the same as for Unix and Linux systems. First install teTeX on your Irix system. Then contact
firstname.lastname@example.org to obtain installation instructions for the TU/e packages (including TU/ePDFScreen and TU/e fonts).
Please specify the teTeX version that you have installed on your system.
