NOTE: EZ has been replaced by MESA.
Please take a look and give it a try if you think it might be useful
for your project. We'll be happy to answer your email questions
to help get it installed and running for you.
The main requirement is the fortran compiler.
The first choice would be ifort 11.1 or later, but if that isn't available,
you can download the current version of gfortran from
GFortranBinaries.
If MESA is more than you want, you might check EZ Web -- a web interface to EZ provided by Rich Townsend at the University of Delaware. Enter the parameters for the run (mass, metallicity, etc.), click submit, and in a few minutes an email arrives with a link to a 'zip' file with the output of the run.
